Servo stabilizer is a system, which provides stable Alternate Current (AC) output voltage where the input power supply voltage changes drastically. It protects the costly equipment from high and low voltage problems.

In layman terms, Servo Voltage Stabilizer is a very simple device which is made by using a combinations of simple electronics and Transformers like Variable Transformer and Buck Boost Transformer and coupled with Servo Motors to regulate the incoming power supply and give us desired regulated output voltage.

A Three Phase Voltage Stabilizer (also known as Three Phase Voltage Regulator) continuously monitors the incoming three phase mains utility supply.
