Servo Controlled Voltage Stabilizer

Servo Contrrol Voltage Stabilizers are highly efficient Voltage regulators that work equally well on any kind of load. It consists of a Detector; a switching unit; a motorized Auto Transformer and Cut Off Circuit. In case of any deviation from the set voltage; the detector send an error signal to the Control Circuit that in turn drives a motor to correct the voltage using the windings on Auto Transformer.
