SCR Power Controller Products

1 Phase, Phase Angle

In phase angle control, each SCR of the back-to-back pair is turned on for a variable portion of the half-cycle that it conducts. Power is regulated by advancing or delaying the point at which the SCR is turned on within each half cycle. Light dimmers are an example of Phase-Angle control.

1032A One Phase Angle120-575 Vac 10-70 Amps @ 55°C Accepts most commands. Field adjustable current limiting.
2022 One Phase Angle120-575 Vac 10-70 Amps @ 55°C Accepts most commands. Dual setpoints for fast transistions.
FUSION Single Phase One Phase Angle or Zero Cross24-600 Vac, 45-65 Hz 50 - 1200 Amps The FUSION single phase AC power controller is a phase angle or zero cross fired controller which linearly controls, with respect to the setpoint, the AC voltage, current, or true power applied to an electrical load.  Control is achieved by means of a pair of inverse parallel SCR’s.
