SCR Power Controller Products

3 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.

FUSION Three Phase Three (3 Leg or 2 Leg Operation) Phase Angle or Zero Cross24 - 600 Vac, 45 - 65 Hz 50 - 1200 Amps The FUSION three 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 a three phase electrical load. The 3 phase controller can be ordered in either 2 or 3 leg control with 2 leg being limited to zero cross firing. Control is achieved for 3 leg by three pairs of inverse parallel SCR’s or in 2 leg by 2 pairs of inverse parallel SCR’s.
