Thyristor Switching Module

Clariant’s Thyristor Switching Module is a fast electronically controlled, self-observing switch for capacitive loads which is capable to switch PFC capacitors within a few milliseconds as often and as long as required without abrasion. Triggering of thyristor is done by means of dynamic power factor relays.
