Three Phase Servo Voltage Stabilizer or servo controlled voltage stabilizer, is consist of isolation transformers, variable transformers, control circuit and sevo motor. When input voltage fluctuation happens, the control circuit will send signal to the sevo motor, and the sevo motor will be running and drive the carbon brush to move on the variable transformer, in this way, it can adjust the ratio of winding, consequently, it makes the output voltage in a stable level.
