Servo controlled voltage stabilizer

The output voltage is maintained at 230 +/- 1 or 415 +/- 1%. The rate of correction is fairly fast. The unit is available in single phase as well as three phase model with balanced load or unbalanced load. A voltmeter is provided to observe the input as well as output voltage. Provision for manual operation is also provided. Solid state control of servo motor. There is no radio interferance or wave form distoration. Insensitive to load power factor. Additional facilites like overload trip facility, auto / visual alaram for over / under voltage, digital voltameter, ameter can be provided. It is available upto 15 kva in single phase and upto 100 kva in three phase. It is tested at - e.r.d.a., baroda.
