ZF2 SCR Power Controls (Three Phase, Two Leg, 350 & 500 Amps)

ZF2 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,twoleg control can be used in most balanced, three phase resistive/heater applications where the load has no neutral connection.
