Model ZF2 SCR Power Control (15-70A) SSR Design (Voltage, Current or Pot Input)
ZF2, Two Leg, Three Phase, Zero Fired, 15-70A for Resistive Loads (Voltage, Current or Potentiometer Input)
ZF2 SCR Power Controls (Two Leg, Three Phase, 15-70 Amps, SSR Type)
ZF2 series SCR power controls are three phase, two controlled leg, zero-fired solid state relay power controls designed to deliver maximum power control with all the reliability of much larger units. 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.
