What Is a Three Phase Servo Voltage Stabilizer?
A three phase servo voltage stabilizer is an electromechanical device that continuously monitors and corrects voltage fluctuations across all three phases in real time. Utilizing a precision servo motor to adjust an internal autotransformer, it ensures the output remains steady—typically at 380V (or a user-defined setpoint), even when the input varies greatly (e.g., 304–456V). This technology is particularly suited to industrial loads like CNC machines, motors, and automated production lines requiring consistent, distortion-free power.
