Model SHZF1 SCR Power Control (70-120A)
SHZF1 SCR Power Controls (Single Phase, 70-120 Amps)
SHZF1 series SCR power controls are single 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.
