ZF3 SCR Power Controls (Three Phase, Three Leg, 60-225 Amps)

ZF3 series SCR power controls are Three phase zero-fired power controls designed to deliver maximum power control and reliability for the most demanding applications. Zero fired units turn on and off full sine waves rapidly for precise power control. The controls use variable time base for very high output resolution. Zero fired, three phase,threeleg control can be used in most three phase resistive/heater load applications.
