Product Description: ZGMVS series HV solid-state soft starter is designed to start a motor. It consists of three-phase antiparallel thyristors cascaded between the power unit and the controlled motor, and the electronic control circuit. It controls the conduction angle of thyristors to make the voltage on the motor vary with the required starts and stops. Such softness has good interference immunity. The trigger system operates stably and reliably. Those thyristors have perfect dynamic/static vo...
