ZF1 SCR Power Controls (Single Phase, 15-70 Amps, SSR Type)

ZF1 series SCR power controls are single phase zero-fired solid state relay power controls designed to deliver maximum power control with all the reliability of much larger units. 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.
