Instructions for Use

1. When measuring voltage, the Ri resistor is connected in series on the primary circuit of the sensor. To achieve optimal accuracy of the sensor, the size of Ri should be selected as much as possible to make the input current around 10mA.
2. Scope of work: Considering the internal resistance of the primary coil (compared to Ri, to maintain the temperature difference as low as possible) and isolation, this sensor is suitable for measuring voltages ranging from 10 to 500V. To ensure the stability of measuring resistance, the power of Ri should be at least 4 times the rated power (usually above 10W). 3. When soldering the sensor to the circuit board, a low-temperature soldering iron should be used, and the soldering time should be as short as possible, otherwise it may cause an open circuit in the internal wiring of the pins.
4. The socket position for installing sensors on the circuit board must be completely consistent with the pin size, and the pins should not be artificially squeezed, otherwise it may cause open circuits in the internal wiring of the pins.

[DC current transformer]LS series Rogowski coil

2026-6-15 20:47:37

I. Overview
Rogowski coil, also known as current measurement coil or differential current sensor, is a circular coil uniformly wound around a non-magnetic material. The output signal is the derivative of current over time. By integrating the output voltage signal through a circuit, the input current can be accurately restored.

II Structure Introduction:
No ferromagnetic material, no hysteresis effect, almost zero phase error; No magnetic saturation phenomenon, therefore the measurement range can range from several amperes to several hundred kiloamperes of current; The structure is simple and there is no direct circuit connection between it and the measured current; The response bandwidth is 0.1Hz-1MHz. Compared with traditional transformers with iron cores, Rockwell coils have a wide measurement range, high accuracy, stability and reliability, response frequency bandwidth, as well as measurement and relay protection functions. They are small in size, light in weight, safe, and meet environmental requirements.
Based on the Rockwell coil, it has the characteristics of real-time current measurement, fast response speed, no saturation, and almost no phase error. Therefore, it can be applied to relay protection, thyristor rectification, variable frequency speed regulation, resistance welding and other occasions with severe signal distortion.

[Miniature transformer]A250 type active transient current transformer

2026-6-15 20:41:25

Technical characteristics and related parameters of A250 active transient current transformer:
Characteristics:

The A250 active transient current transformer does not contain ferromagnetic materials, has no hysteresis effect, and has almost zero phase error; There is no magnetic saturation phenomenon, so the measurement range can range from several amperes to several hundred kiloamperes of current; The structure is simple and there is no direct circuit connection between it and the measured current; The response bandwidth is 0.1HZ-1MHz. Compared with traditional transformers with iron cores, it has a wide measurement range, high accuracy, stability and reliability, response frequency bandwidth, as well as measurement and relay protection functions. It is small in size, light in weight, safe, and meets environmental protection requirements. Due to the characteristics of real-time current measurement, fast response speed, no saturation, and almost no phase error, this type of current transformer can be applied in situations where signal distortion is severe, such as relay protection, thyristor rectification, frequency conversion speed regulation, resistance welding, etc.

Disadvantages:
Due to limitations in manufacturing processes and materials, the accuracy of a normal 50Hz sine wave is not as good as that of conventional transformers. It can reach a maximum level of 0.2.

Parameters:
Input current: 0-300A
Output voltage: current differential di/dt 1mV5%/A (50Hz)
Response frequency: 1Hz~500KHz
Linearity: 0.5%, 0.2%
Appearance: 17X16X19 5 through-hole mm

Mainly used for measuring severely distorted sine wave current, impulse current, and pulse current (cannot measure pure DC current).
Note: YX250 series transformers can be customized according to user requirements.

The usage method of GLD200 mining current sensor
1. Wiring: The output wiring should be strictly wired according to the colors marked below.
a. Sensor wiring instructions
Red wire - positive pole of power supply (aviation plug pin 1)
Black wire - negative pole of power supply (2nd pin of aviation plug)
Yellow line - frequency signal (current type) output (aviation plug pin 3)
Green wire - power-off signal (current type) output (aviation plug pin 4)
b. Connection method of sensing head
a) In the wiring compartment of the switchgear, pass the wire to be tested through the current transformer;
b) The transformer outputs a current signal of 0-5A based on the detected current flowing through the detection wire, and connects the current signal to the current transmitter;
c) The current transmitter converts the 0-5A current signal into a 4-20mA intrinsic safety signal output, which is connected to the input aviation socket of the sensor.
2. Remote control: The button functions are as follows:
Select key ": Select the debugging function.
"Confirm key": confirm the selection of parameters, press this key after selecting parameters, which means that the parameters of the current calibration function will be stored in memory and the commissioning work will be completed.
�� ": Up key - Press the up key once to increase the debugging data by 1;
�� ": Down key - Press the down key once to subtract 1 from the debugging data;
Attention: Once the parameters of the instrument have been adjusted, the selection button on the remote control must be pressed before power off to make the function prompt disappear. Otherwise, the adjusted parameters will not be stored in the memory, resulting in the invalidity of this adjustment!!!

Instructions for Use
1. Incorrect wiring may cause damage to the sensor. After the sensor is powered on, when the measured current passes through the direction of the sensor arrow, the in-phase current value can be measured at the output terminal.
2. The current input terminal of the sensor should be firmly and reliably soldered to the circuit board, and the width of the input terminal wire on the printed board should not be less than 1.5mm, the shorter the better. It is best to use double-sided epoxy board and double-sided wiring on the printed board to avoid overheating caused by long-term operation.
3. According to customer requirements, the original pins can be changed to four pins: 1, 3, and 6, 8.
