[dual power switch]CCQ2 Series Dual Power Switching System

2026-6-16 12:38:42

Scope of application
The CCQ2 dual power automatic switching device (hereinafter referred to as CCQ2) is suitable for two power sources (common power source and backup power source or power generation power source) with AC 50Hz, 690V and below. It automatically switches between power sources when one power source fails to ensure the reliability and safety of power supply. This product complies with the IEC 60947-6 "Automatic Transfer Switchgear" standard of the International Electrotechnical Commission.

3. Model and its meaning

4. Structure and Performance
4.1 Structure
The CCQ2 dual power automatic switching device is a switching system consisting of two main parts: the device body and the automatic controller, which are connected by a dedicated cable with a maximum length of 2m. The device body consists of two circuit breakers with electric operating mechanisms and accessories (auxiliary and alarm contacts), mechanical interlocking mechanism, fuses, wiring terminals, etc. (hereinafter referred to as the device), all components are installed on a metal base plate, and the mechanical interlocking mechanism is installed between the two circuit breakers. The control power supply voltage of the device is AC230V, and the mechanical life is 5000 times for CCQ2-63~225, 3000 times for CCQ2-400, and 2500 times for CCQ2-630~800.
The automatic controller has a complete plastic shell, installed on the door panel of the box or cabinet, and uses advanced and reliable electronic components to form a complete control circuit inside. The working power supply voltage of the automatic controller is AC230V.

4.2 Performance
The CCQ2 series dual power switching system simultaneously detects the voltage of two power sources. The power supply voltage that is higher than 110% of the rated value is judged as overvoltage, while the power supply voltage that is lower than 85% of the rated value is judged as undervoltage. The logic circuit makes logical judgments on the above detection results, and the processing results drive the corresponding command relay to issue opening or closing instructions to the electric operating mechanism through the delay circuit. The above detection results are displayed on the panel with light-emitting diodes.
Automatic controllers can be divided into three types based on their control functions: self switching and self restoring (R), self switching and non self restoring (S), and grid power generation (F). The first two types are suitable for the grid power supply system, while the latter type is suitable for the grid power generation system.
4.2.1 The automatic controller (CCQ2R) with self switching and self recovery automatically switches between two power sources (referred to as the common power source and the backup power source). Under normal conditions, it should be powered by the common power supply. When there is an abnormality in the common power supply (overvoltage, undervoltage, or phase loss in any phase voltage), it will automatically switch to the backup power supply after a set delay; After the commonly used power supply returns to normal, it will automatically return to the commonly used power supply after a set delay; When there is an abnormality in the backup power supply (overvoltage, undervoltage, or phase loss in any phase voltage), the controller emits a backup power alarm sound, which can also be manually turned off.
The functions of the self switching and self resetting automatic controller are shown in Table 1.

Table 1

common power supply	backup power supply	Control function
normal	normal	Common power supply: Q2 split, Q1 combined
normal	abnormal	Common power supply, backup power supply abnormal alarm (can be turned off)
abnormal	normal	Q1 opens after t1 delay, and Q2 closes after t2 delay - backup power supply
return to normal	normal	After a delay of t3, Q2 opens, and after a delay of t4, Q1 closes - restoring normal power supply

Note: Q1 on and Q1 off indicate the closing and opening of the circuit breaker that controls the common power supply;
Q2 on and Q2 off indicate the closing and opening of the circuit breaker that controls the backup power supply;
T1: Conversion disconnection delay (maximum 60 seconds, minimum 1.5 seconds, factory set at 20 seconds);
T2: Switching on delay (maximum 2 seconds, minimum 0.7 seconds. Factory set at 1 second);
T3: Return disconnect delay (maximum 60 seconds, minimum 1.5 seconds, factory set at 20 seconds);
T4: Return connection delay (maximum 2 seconds, minimum 0.7 seconds, factory set at 1 second);
The delay setting value is free from user self adjustment. The user requests to set it at another time. Please specify when placing an order.
4.2.2 The automatic controller (CCQ2S) that automatically switches between two power sources (referred to as the common power source and the backup power source, respectively). When there is an abnormality in the common power supply (overvoltage, undervoltage, or phase loss in any phase voltage), it automatically switches to the backup power supply after a set delay. However, when the common power supply returns to normal, it cannot automatically recover until the backup power supply has an abnormality before switching.
The functions of the automatic controller with automatic switching and non automatic recovery are shown in Table 2.

Table II

T2: Switching on delay (maximum 2 seconds, minimum 0.7 seconds, factory set at 1 second);
The delay setting value is free from user self adjustment. The user requests to set it at another time. Please specify when placing an order.
4.2.3 Grid - The automatic controller for power generation (CCQ2F) automatically switches between the grid and the two power sources. When the grid voltage is below 85% of the rated voltage, a power generation command is issued through a power generation delay command (output through a set of normally open and normally closed contacts). When the generated voltage reaches 85% of the rated voltage, the load circuit is first disconnected from the power grid. After a delay in the unloading instruction, the unloading instruction is issued to remove the secondary load (output through another set of normally open and normally closed contacts), and then the generated power supply is connected through a conversion delay. After the grid voltage returns to normal (reaching 85% of the rated voltage or above), the load circuit is disconnected from the power source after a return disconnection delay, and then automatically switched to grid power supply after a return connection delay. The power generation delay (t5=2100 seconds) is adjusted and set by the potentiometer on the right side of the panel (set to 20 seconds at the factory), and the return disconnection delay (t3=1.5 60 seconds) is adjusted and set by the potentiometer on the left side of the panel (set to 20 seconds at the factory).
The functions of the power grid power generation automatic controller are shown in Table 3

Table 3

Grid power supply	Power generation source	Automatic control function
normal	Not generating electricity	Power supply from the power grid; Q2 division, Q1 combination
abnormal	No power generation	After a delay in issuing the power generation command, the generator set generates electricity
abnormal	Normal power generation	After a delay of T2, Q1 opens and Q2 closes, powered by the power generation unit
return to normal	normal	Request power outage. After a delay of T1, Q2 will be disconnected and Q1 will be closed, automatically restoring power supply to the common power source

Note: Q1 on and Q1 off indicate the closing and opening of the circuit breaker that controls the common power supply;
Q2 on and Q2 off indicate the closing and opening of the circuit breaker that controls the backup power supply.

[dual power switch]SRMQH2/63-1250 type dual power switch

2026-6-16 12:38:04

Model meaning

Intelligent controller function
SRMQH2 is a new intelligent dual power conversion switch. The intelligent controller is equipped with keyboard input and LCD display, which can synchronously detect the common power supply (N) and backup power supply (R) in three phases. It has the function of detecting overvoltage, undervoltage, phase failure or loss of voltage. When it is higher than 120% of the rated working voltage value, it is judged as overvoltage, and when it is lower than 75% of the rated working voltage value, it is judged as undervoltage. The backup power supply (R) fault alarm and double division are triggered. The microcomputer processes the detection results and issues corresponding instructions. The processing results can be displayed on the LCD, providing users with a good human-machine dialogue interface. The alarm can also be manually closed by pressing the button. At present, regardless of the working mode, the microcomputer detects abnormal data and delays for 3 seconds to disconnect the abnormal power supply and enter the dual protection state. After a delay of 0-30 seconds, it switches to normal power supply.
Example: In the self switching and self recovery mode, if the common power supply (N) fails, it will automatically switch to the backup power supply (R) for power supply. If the common power supply (N) returns to normal, it will automatically return. If both working power supplies fail, the microcomputer will issue a double split command after 3 seconds. If the power supply returns to normal, it will be prioritized for operation.

Structure and Function
This intelligent conversion switch consists of two main parts: a microcomputer controller and a switch conversion device, which are connected by dedicated cables.
The switch consists of a microcomputer controller, a micro motor, a gear box, a micro switch, an operation keyboard, an LCD display, a molded case circuit breaker, etc. Equipped with automatic, manual, and dual split operation; The characteristics of mechanical and electrical dual interlocking maximize the satisfaction of power supply and distribution needs.
The switch has three status positions for users to choose from: common power (N) on, double off, and backup power (R) on. The switch has the characteristics of small size, light weight, stable operation, and easy use.

Self investment and self recovery (R) power grid and power grid
Self investment non self recovery (S) type power grid and power grid
Self investment and self recovery (F) type power grid and power generation
(Additional fire protection function (DC24V) can also be added)

Self investment and self restoration (R) power grid - power grid
At the initial startup, it is automatically powered by the commonly used power supply. When there is an abnormality in the power supply (overvoltage, undervoltage, undervoltage, or phase failure), the NA, NB, NC, RA, RB, and RC on the controller LCD will disappear accordingly. The common power supply (N) will automatically switch to a dual split state after 3 seconds of abnormal operation, and then switch to the backup power supply (R) for power supply after a delay of 0-30 seconds. The delay time can be set to 3 seconds at the factory. When the common power supply returns to normal, it will automatically switch from the backup power supply to the common power supply (N) for power supply; The backup power supply (R) is abnormal, and the controller will emit a "beep" alarm sound. This alarm can also be manually turned off. The word 'alarm' disappears on the LCD, indicating that the alarm system has been turned off and there is no 'alarm' function at this time. Pressing the down key will display the word "alarm" and make a beep at the same time, indicating that the alarm system has been turned on.
At the initial startup, it is automatically powered by the commonly used power supply. When there is an abnormality in the power supply (overvoltage, undervoltage, undervoltage, or phase failure), the NA, NB, NC, RA, RB, and RC on the controller LCD will disappear accordingly. The commonly used power supply (N) will automatically switch to a dual split state after 3 seconds of abnormality, and then switch to the backup power supply (R) for power supply after a delay of 0-30 seconds. The delay time can be set to 3 seconds at the factory.
After the common power supply returns to normal, the backup power supply (R) cannot automatically return to the common power supply (N) and needs to be manually returned; At this time, the backup power supply (R) is also abnormal, and the controller will emit a "beep" alarm sound. At the same time, if the power supply is restored to normal after switching to the double split position, priority should be given to putting it into operation. This alarm can also be manually turned off. The disappearance of the LCD "alarm" indicates that the alarm system has been turned off, and there is no "alarm" function at this time. Pressing the down key will display the word 'alarm', and a beep will sound at the same time, indicating that the alarm system has been turned on.

Self investment and self restoration (F) power grid - power generation
The controller detects the common power source (N) and the power generation source (R). When the common power source (N) is abnormal, the control system sends a power generation command (normally open contact) to the generator set to start it. When the voltage of the generator set reaches the normal working voltage value, the controller sends a command to put the power generation source into use, ensuring the normal operation of the generator set. When the voltage of the generator drops below 75% of the rated value, the control system automatically disconnects the load and enters a double split state. After the grid voltage (N) returns to normal, the intelligent system will automatically return from the backup power source (R) to the common power source (N) for power supply after a delay, and the generator set needs to be manually shut down.

·Introduction to the Three Control Functions of CA1 Series Automatic Transfer Switch Controller: R-Type, S-Type, and F-Type
·Automatic switching and restoration between power grids (R-type)
The R-type controller automatically switches between two power sources, namely the common power source and the backup power source. When in normal condition, it should be powered by the common power supply. When there is an abnormality in the common power supply (overvoltage, undervoltage, phase loss, or power outage of the detected phase voltage), it will automatically switch to the backup power supply after a set delay time; After the common power supply returns to normal, it will automatically return to the common power supply after the set delay time.

The functions of the R-type controller are shown in the table below:

common power supply	backup power supply	control function
normal	normal	Common power supply: Q1 on, Q2 off
abnormal	normal	After t1 delay, Q1 is divided, and after t2 delay, Q2 is closed - backup power supply
return to normal	normal	After a delay of t3, Q2 is divided, and after a delay of t4, Q1 is closed - restoring normal power supply

Note: Q1 on and Q1 off indicate the closing or opening of the circuit breaker that controls the common power supply;
Q2 on and Q2 off indicate the closing or opening of the circuit breaker that controls the backup power supply.
Self switching and non self recovery between power grids (S-type)
The controller that automatically switches between two power sources (referred to as the common power source and the backup power source, respectively) without self restoration. When there is an abnormality in the commonly used power supply (overvoltage, undervoltage, phase loss, or power outage of the detected phase voltage), it automatically switches to the backup power supply after a set delay. However, when the commonly used power supply returns to normal, it cannot automatically recover. Only switch when there is an abnormality in the backup power supply.

The functions of the S-type controller are shown in the table below:

common power supply	Backup power supply	control function
normal	normal	Common power supply: Q1 on, Q2 off
abnormal	normal	After t1 delay, Q1 is divided, and after t2 delay, Q2 is closed - backup power supply
return to normal	normal	Still powered by backup power supply
normal	Abnormal	After a delay of t3, Q2 is divided, and after a delay of t4, Q1 is closed - powered by a common power supply

Note: Q1 on and Q1 off indicate the closing or opening of the circuit breaker that controls the common power supply;
Q2 on and Q2 off indicate the closing or opening of the circuit breaker that controls the backup power supply.
Self switching and self restoration between power grid and power generation source (F-type)
The F-type controller automatically switches between two power sources, namely the grid power source and the power generation power source. When there is an abnormality in the power supply of the grid (overvoltage, undervoltage, phase loss, or power outage of the detected phase voltage), the controller delays the power generation command and sends a power generation command request. When the power supply voltage reaches 50% to 90% of the rated voltage (for Q-type converters) or 70% of the rated control power supply voltage (for W-type adapters), the device disconnects the load circuit from the grid and automatically switches to the power supply. After the grid voltage returns to normal, it automatically returns to the grid for power supply and issues a command to stop power generation.

Grid power supply	Power generation source	control function
normal	No power generation	Grid power supply: Q1 on, Q2 off
abnormal	No power generation	Delayed issuance of power generation command t5, waiting for power generation
abnormal	normal	After a delay of t1, Q1 is divided and an unloading instruction is issued. After a delay of t2, Q2 is closed - the power supply is used for power generation
return to normal	normal	After the stable time of the power grid reaches the t6 setting value, a command to stop power generation is issued. After a delay of t3, Q2 is divided, and then after a delay of t4, Q1 is closed - automatically returning to the power grid for power supply

Note: Q1 on and Q1 off indicate the closing or opening of the circuit breaker that controls the power supply of the power grid;
Q2 on and Q2 off indicate the closing or opening of the circuit breaker that controls the backup power supply.

Control characteristics of R-type, S-type, and F-type automatic controllers:

Model and meaning

Structural characteristics
The DTSQ1 intelligent dual power automatic switching system (hereinafter referred to as the intelligent system) consists of two main parts: the device body and the intelligent automatic controller.
1. The device body consists of two circuit breakers with motor operating mechanisms (model specifications refer to the technical parameter terms) and accessories (auxiliary alarm contacts, etc.), mechanical interlocking mechanism, electrical interlocking, fuses, wiring terminals, etc. All components are installed on a metal plate.
2. The intelligent automatic controller is composed of a novel microcontroller and various output modules.
The two are connected through a dedicated aviation plug interface and a shielded cable with a length not exceeding 2 meters to form an intelligent control system. The intelligent system controls the power supply voltage to be 220V, 50/60Hz.
This intelligent system has dual mechanical and electrical interlocking protection functions, providing a safe and reliable guarantee for your power supply.
This intelligent system can automatically switch between dual power supply of three-phase three wire and three-phase four wire.

Performance of DTSQ1 series intelligent dual power automatic switching system

One Working principle of intelligent system
The controller simultaneously detects two voltages, and determines overvoltage for power voltages higher than 110% (adjustable) of the rated value and undervoltage (or loss) for power voltages lower than 85% (adjustable) of the rated value. The microcomputer control circuit logically judges the above detection results, and the processing results are sent to the electric operating mechanism through a delay (adjustable) circuit to drive the corresponding instructions to open or close the circuit. The above detection results can be displayed on the LCD screen of the intelligent automatic controller panel, or connected to the computer through a serial port and controlled by software for users to find the cause, so that users can repair the faulty line in the shortest time and restore the dual power supply to its original state.

II Intelligent automatic controllers are divided into three types according to their control functions
Self investment and self recovery (R) are applicable to power grids. The intelligent automatic controller automatically switches between two power sources, namely the common power source and the backup power source. When the common power source fails or is abnormal (overvoltage, undervoltage, undervoltage or phase loss of any phase voltage), it automatically switches to the backup power source after a set (adjustable) delay time. When the common power source returns to normal, it automatically returns to the common power source after a set (adjustable) delay time. When the backup power source fails or is abnormal (overvoltage, undervoltage, undervoltage or phase loss of any phase voltage), the controller issues an alarm for the common or backup power source.
Self investment without self recovery (S) is applicable to power grids. The automatic controller that automatically switches between two power sources (i.e. the common power source and the backup power source) without self recovery. When any power source experiences an abnormality (overvoltage, undervoltage, or phase loss in any phase voltage), it will automatically switch to another normal power source for recovery after a set delay.
Grid and Power Generation (F) [When used in a grid and power generation system, the conversion time should be set to 15 seconds] The automatic controller for grid and power generation automatically switches between the two power sources. When the grid voltage is below 85% of the rated voltage, a power generation delay command is issued (output through a set of normally open and normally closed contacts). When the generated voltage reaches 85% of the rated voltage, the load circuit is first disconnected from the power grid, and the secondary load is removed (output through another set of normally open and normally closed contacts) through unloading instructions. Then, the generated power supply is connected with a delay through conversion. After the power grid returns to normal (reaching 85% of the rated voltage or above), the intelligent controller will automatically disconnect the load circuit from the power source and switch to power supply from the grid.

III When the commonly used power supply is abnormal, the microcomputer will detect whether the working state (manual, automatic, self recovery, non self recovery, etc.) and the pre-set backup power supply are normal to decide whether to switch. The startup backup power supply will be used, and the system load will be powered by the backup power supply.

4 Dual power supply dual split state:
When the system is loaded in a dual split state, regardless of whether the two power supplies are normal or the preset states of "manual" and "automatic", the system still remains in a dual split state. Only after operating the keyboard (manual) (automatic), will the system be switched to a non dual split state (manual - common - standby or automatic - self recovery - no self recovery), and the load will be powered and processed as described above.
Five Protection function:
Overload and short circuit protection for phase failure, open circuit protection for voltage loss, and undervoltage protection
VI Equipped with automatic switching time adjustable from 1 second to 30 seconds
7 High performance microcontroller program control, strong anti-interference ability, high protection accuracy
8 It has the advantages of small size, high stability, and reliable continuous operation
Nine Equipped with a central microcomputer controlled communication interface
Ten Silent operation, energy-saving and consumption reducing, in compliance with national green electrical product standards
Eleven Equipped with remote control of fire signal output

Fire control signal
The switch has a normally open contact for external connection to provide users with fire control signals. When a fire occurs, the fire control center sends a control signal to enter intelligent control. At this time, the dual power supply body enters the open state and cuts off the power supply at the load end. When the fire signal is not released, regardless of whether it is in the "manual" or "automatic" state, the common and backup power supply execution switches of the automatic transfer switch cannot be closed. Only after the fire control signal is released, the switch automatically switches to normal power supply from the common power source.

function

Control function:
The "normally" switch in the three status positions is closed, and the "standby" switch is open; The 'backup' switch is closed; The 'normally' switch is disconnected; Both switches are disconnected to the 0 position.
Multiple operation modes: emergency manual operation, manual control operation, automatic control operation.
The switch is controlled by a single-chip control device to achieve automatic operation function, and the reliable working voltage of the control motor of the main circuit is: the upper limit is 220 × 115% V, the lower limit is 220 × 75% V, and the frequency is 50HZ+10%.

Detection and protection function:
The working voltage of the various wiring terminals of the power supply is considered overvoltage when it reaches 115% of the rated working voltage; When the working voltage of the various wiring terminals of the power supply drops to 75% of the rated working voltage, it is considered undervoltage; If the working voltage of any phase terminal of the power supply drops to 75% or below of the rated working voltage, it is considered as voltage loss, which is abnormal. The common power supply and backup power supply are both part of the mains power supply system, and one power supply can be determined as the common power supply. When any phase of the common power supply circuit loses voltage, the switch will automatically switch to the backup power supply circuit after a delay of 3 seconds. When the common voltage circuit returns to normal, the switch will automatically switch to the common power supply circuit after a delay of seconds; The commonly used power supply circuit is the mains power supply, and the backup power supply circuit is the power supply system of the oil engine. When any phase of the commonly used power supply circuit loses voltage or all phases simultaneously experience overvoltage or undervoltage, the momentary switch will automatically switch to the disconnect position after a delay. At the same time, the control device will send a signal to start the oil engine. After the start is complete (i.e. no fault), the momentary switch will automatically switch to the backup circuit of the oil engine after a warm-up delay. When the backup power circuit of the oil engine is supplying power and the common power circuit returns to normal, after a delay of 3 seconds, the switch automatically switches to the common power circuit.
When the backup power circuit of the oil engine is supplying power, if any phase loses voltage or all phases simultaneously experience overvoltage or undervoltage, and if the common power circuit returns to normal, the switch will automatically switch to the disconnected position after a delay of 3 seconds.
When the switch is in the off position, as long as the common power circuit returns to normal and after a delay of 3 seconds, regardless of the state of the oil machine, the switch will automatically switch to the common power circuit first. When both the common power supply and the backup power supply fail, the switch should automatically switch to the disconnected position.
When the common power supply and the backup power supply lose voltage or undervoltage to 220 × 75% or below simultaneously, the switch fails and remains in its original position.
Computer communication function:
After connecting to the computer, this machine can directly monitor and control the conversion switch (please specify this function when ordering).

Function annotation:
Self investment and self recovery (R) are applicable to power grids. After the commonly used power supply returns to normal, it will automatically return to the commonly used power supply after a set (adjusted) delay time.
Self investment without self recovery (S) is applicable to power grids. The automatic controller that automatically switches between two pairs of intermediate power sources (i.e., the common power source and the backup power source) without self restoration. When any power supply experiences an abnormality (overvoltage, undervoltage, or phase loss in any phase voltage), it will automatically switch to another power supply after a set delay. However, when the abnormal power supply returns to normal, it cannot automatically recover.
When used in the power grid and power generation system, the self controller automatically switches between the power grid and the two power sources. When the grid voltage is below 85% of the rated voltage, a power generation command is issued through a power generation delay command (output as a set of normally closed contacts). When the generated voltage reaches 85% of the rated voltage, the load circuit is disconnected from the power grid first, and then the generated power supply is connected after a delay. After the power grid returns to normal (reaching 85% of the rated voltage or above), the intelligent controller will automatically disconnect the load circuit from the power source and switch to power supply from the grid

Fire release device:
DC24V is added, immediately cut off the two currents.

Switching, when the grid voltage is below 85% of the rated voltage, a power generation command is issued through a power generation delay command (output through a set of normally open and closed contacts) When the generated voltage reaches 85% of the rated voltage, the load circuit is first disconnected from the power grid, and the secondary load is unloaded (output through another set of normally open and closed contacts) through unloading instructions. Then, the generated power supply is connected with a delay through conversion After the power grid returns to normal (reaching 85% of the rated voltage or above), the intelligent controller will automatically disconnect the load circuit from the power source and switch to the power grid for power generation based on logical judgment
When the commonly used power supply is abnormal, the microcomputer will detect the current preset working status (manual, automatic, self resetting, non self resetting) and whether the backup power supply is normal to decide whether to switch and start the backup
Using power supply, the system load is powered by a backup power source
