Control Concepts Single Phase Phase Angle SCR
SINGLE PHASE, PHASE ANGLE
In phase-angle control, each SCR of the pack-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.
The following models are suited for applications with
Single Phase, Phase Angle requirements.
