SHZF2 SCR Power Controls (Three Phase, 15-25 Amps)

SHZF2 series SCR power controls aretwo leg, three phase zero-fired power controls designed to deliver maximum power control and reliability for the most demanding applications. Two leg control is suitable for most three phase heater loads with that have no neutral or ground connection. 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.
