Thyristor Switch is an electronic power unit which can switch on/off the shunt capacitors fast. Its main loop adopts anti-parallel thyristor module. It supports level and pulse control ways which is suitable for low voltage capacitor fast switch on/off.This thyristor Switch can be used while power grid system harmonic distortion is high or in LC reactive filter installations.
Feature
Use good brand SCR, high reliability and stability
MCU control precise trigger, software correction trigger timing for true zero switching
While switching capacitor, no flow, no overvoltage, no sparks, fast response time of less than 15ms
Support level and pulse trigger mode, the trigger mode is flexible and easy to replace transform.
Use optical isolation to avoid interference
Phase lack alarm with overheat protection
