SHZF3 SCR Power Controls (Three Phase, 120A Amps)
SHZF3 series SCR power controls are three leg, three phase zero-fired power controls designed to deliver maximum power control and reliability for the most demanding applications. Zero fired, three phase, three leg control can be used in most three phase resistive/heater load 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.
