Three Phase Servo Voltage Stabilizer

Three Phase Servo Voltage Stabilizer

Approx Price: Rs 21,000 / onwards 
We manufacture a range of Three Phase Servo Voltage Stabilizers that are primarily used to protect the various electronic equipment such as fridge and others, that are affected by the fluctuation in the input of the mains supply. At times the equipment do not function properly when they are not used at the specified voltage. Servo voltage stabilizers (single and three phases) with sensitive electronic and electrical equipment hold a lot of importance as they increase the operational life of expensive appliances, CNC machines, electrical equipment, motors lab equipment, medical equipment.

The servo controlled voltage stabilizer connects the AC voltage which is not stabilized and dips at one point of time and at other point of time rises to very high value.
