1.Product Introduction

The SQ-TS SCR switch is composed of a trigger circuit, a thyristor and a differential auxiliary circuit. The trigger circuit judges and outputs a control signal (DC12V) when the voltage crosses zero to make the SCR turn on or turn off. The conditional circuit can reliably guarantee the output of the control signal, mainly for heat conduction and heat dissipation, with built-in over-temperature protection and a temperature switch that controls automatic operation, thus providing a good effect for operation.

Compared with other switches, this thyristor switch has no inrush current and no contact noise during switching and is more suitable for occasions where load switching changes are complicated, such as elevators, cranes and welding machine-based power distribution system.

2.Product Features

1.Zero-crossing switching, no inrush current and no power grid voltage flicker during switching.

2.Built-in cooling fan, automatic control fan with turn off and turn off function. Built-in over-temperature (80°C) protection.

3.The LED signal light shows the switching status.

4. Integrated integration, small size and easy installation. Fully cast structure, strong and durable. Terminal blocks are interchangeable horizontally and vertically.

5. Photoelectric isolation, strong anti-interference ability, fast response (10ms).

6. There is no noise in switching and no mechanical wear, which greatly prolongs the service life.
