PSQ series angular stroke intelligent electric actuatorDetailed product description：

Overview: The PSQ actuator is a product launched by PS Automation GmbH, a manufacturer of actuators in Germany. The PSQ series angular stroke electronic integrated electric actuator is small in size, light in weight, powerful in function, equipped with an intelligent operator, and easy to operate. The PSQ series angular stroke electric actuator has an output torque of 50Nm-700Nm with a 90 ° angular stroke, suitable for 90 ° rotary valves (such as ball valves and butterfly valves) and air door switch or adjustment control.
Feature 1: Integrated structural design, the position transmitter and servo amplifier can be directly installed inside the actuator as two independent components, directly receiving 4-20mA control signals and outputting 4-20mA or 1-5VDC valve position feedback signals. It has self diagnostic function and is very convenient to use and calibrate.
2. Functional modular structure design, through the combination of different optional functions, achieves control from simple to complex, meeting different application requirements.
3. The structure is simple, compact in size, lightweight, easy to install and maintain, and all mechanical parts are made by CNC machining with exquisite craftsmanship.
4. The transmission adopts small backlash sealed gears, which have high efficiency, low noise, long service life, stability and reliability, no need for refueling, and multiple operating speeds to meet the requirements of various control systems, ensuring fast response and stability of the system
5. The PSQ series has torque switch protection to prevent damage to the valve stem due to excessive torque generated by the valve.
6. The driving motor is a high-speed synchronous motor made of high-performance rare earth magnetic materials, which runs smoothly. It has the characteristics of small size, high torque, anti blocking, and high control accuracy.
7. Segmented adjustment can be set, that is, the dual time proportional signal output by one regulator controls two actuators (4-12mA corresponds to fully open or fully closed PSL1, 12-20mA corresponds to fully open or fully closed PSL2).
8. The valve position feedback component adopts a fully sealed high-precision multi turn potentiometer, which has the characteristics of small volume, high accuracy, small dead zone, and long service life. All electrical components are made of world-renowned brand products with reliable quality. The wiring of electrical components is rigorous and completely isolated from transmission components, which improves the reliability of the operation of the actuator.
The PSQ angular stroke actuator is mainly composed of an isolated electrical control part and a gear transmission part, with the motor serving as the intermediate component connecting the two isolated parts. The motor torque is transmitted to the planetary gears through the main gear, and the main gear drives the planetary gears to drive the hollow gears. Hollow gears have three fewer teeth than secondary gears, so they can be driven by planetary gears. When a planetary gear rotates once, the hollow gear rotates three teeth, and the outer part of the planetary gear always meshes with a worm gear, which does not separate during operation. This design allows the motor to be manually controlled through the handwheel in case of faults or unexpected increases in valve torque.
The actuator has two threaded stop mechanisms and two limit switches to achieve electrical limit. The stroke range of each turn can be controlled by the position of the limit switch. The valve opening is indicated by a protruding display, and the unique torque switch can adjust the maximum torque from 50% to 100%, achieving torque protection to prevent valve stem damage caused by valve jamming

Intelligent controller PSAP4

PSAP4 is an intelligent proportional servo circuit for PS electric actuators, which adopts SMT technology and has the characteristics of small size and high reliability. This circuit will control the 4-20mA current signal of the electric actuator, compare it with the current position signal of the actuator, and control the opening or closing action of the actuator according to the deviation situation, so as to balance the position of the actuator with the input signal. PSAP4 not only implements the action of the actuator with the input 4-20mA signal, but also provides a set of 4-20mA position signals isolated from the working power supply and input signal to the system. PSAP4 can easily adjust the starting position and stroke of the actuator; Can easily switch between positive and negative effects; Set the actuator to fully open, fully closed, or hold state when the input signal fails.
The working principle of the position signal conversion circuit is to convert the change of the 1000 ohm three wire sliding resistance signal reflecting the position of the actuator into 4-20mA. The control input and position signal are simultaneously sent to the deviation amplifier for comparison, and the comparison result controls the on/off of the solid-state switch, realizing the on/off control of the actuator. Adjusting sensitivity according to control requirements can change tracking accuracy and eliminate oscillations that may occur due to mechanical inertia.

The additional travel (2WE) and additional torque (2DE) switches are paired with two additional switches, which can output two passive contact signals (220VAC 5A) when the actuator reaches the appropriate position or torque.
The single/double valve position feedback potentiometer (POT/POT2) outputs 1 group (POT) or 2 groups (POT2) of 0-1000 Ω resistance signals corresponding to the same valve position value, which are used as valve position feedback input signals for the servo amplifier or transferred to the instrument for valve position display.
The heating resistor (HR) is installed inside the actuator to maintain a certain temperature inside the actuator, in order to avoid frost formation and damage to the electrical components of the actuator when used at low temperatures (below -20 ℃).
When the independent position transmitter PSMF does not require a built-in servo amplifier and only needs to output a 4-20mA valve position signal, it is selected
