Silicon Controlled Rectifiers Most Chromalox power packs utilize Silicon Controlled Rectifiers to control power. A Silicon Controlled Rectifier (SCR) is a semiconductor rectifier that has the added feature of controllability. The SCR is capable of conducting OR blocking current in the forward direction, depending upon the gate signal.
