Single Phase Servo Voltage Stabilizer is used to protect any critical equipment, which are effected by the fluctuation in the input supply and those equipments do not operate when they are not used at the specified voltage. The Servo Voltage Stabilizer provides constant output with tolerance of +/-1% that makes equipments efficient in operation. The Servo Voltage Stabilizer works using 170 – 270 V in single phase mode of operation. Single Phase Servo Voltage Stabilizer also protects equipments from being damaged due to high and low voltage.
