SHPF1 SCR Power Controls, Phase Angle (Single Phase, 70-120Amps)

SHPF1 series SCR power controls are single phase, phase angle fired SCR power controls designed to deliver maximum power control with very high reliability. Phase angle fired units delay the turn on point in each half cycle of the sine waves for precise power control. This model can be used with resistive, inductive and transformer coupled loads. When the optional current limiting is utilized this model can be used with heaters that have a significant change in resistance during heat up. Other common applications for this model include IR heating and vibratory feeders.
