Model SHZF3 SCR Power Control (15-25A)
SKU: SHZF3 15-25A
SHZF3, Compact Size, Three Phase, Three Leg, Zero Fired, SCR Power Control, 15-25A for Resistive Loads
SHZF3 SCR Power Controls (Three Phase, 15-25Amps)
SHZF3 series SCR power controls arethree leg, three phase zero-fired power controls designed to deliver maximum power control and reliability for the most demanding applications.Zero fired, three phase,threeleg 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.
