SCR Power Regulators

Power Controllers for Precise Voltage and Current Control

SCR Power Regulators, also known as Thyristor Power Controllers are devices that control power delivery. They are designed to vary the AC voltage across resistive and inductive loads. The primary controlling device is a back-to-back connected Silicon Rectifier (SCR) or Thyristor. They are coupled with the triggering electronics from Libratherm which provide gate cathode triggering pulses proportional to the control signal. This controls the conduction angle of the thyristor which controls the average AC voltage across the load. Regulating the AC voltage controls the AC current drawn by the load and thereby controls the power delivered to the load.
