SERVO CONTROLLED VOLTAGE STABILIZERS
Integrated ‘STAVOL’ Voltage Stabilizers are Electro Mechanical Servo Controlled Voltage Stabilizers in which Integrated Circuit (IC) control units are employed to provide high reliability as well as a long and maintenance-free service.

Integrated ‘STAVOL’ Voltage Stabilizers are extremely efficient Stabilizers which meet the requirements of majority of voltage control problems like Under-Voltages, Over-Voltages, Chronic Low Voltage and Voltage Fluctuations due to user owned Generators.

High Speed of correction without hunting or overshoot and very high reliability are the special features of Integrated ‘STAVOL’ Line Voltage Stabilizers.

Integrated ‘STAVOL’ Voltage Stabilizers essentially consist of a Toroidal Auto-transformer, a Buck-Boost Auxiliary Transformer, an AC Synchronous Motor and a Solid State Electronic IC control unit.

Features
  • All Solid State Electronic IC Control Circuits.
  • High Speed of Response.
  • No Overshoot or Hunting.
  • AC Step Synchronous Motor for High Reliability.
  • High Accuracy upto + 1% in any model (Optional).
  • Zero Waveform Distortion.
  • Unaffected by Load Power Factor.

Three Phase Operation

For Three Phase Operation, 3 numbers of Single Phase Units are connected in STAR which will take care of Input unbalanced voltage as well as output unbalanced load conditions.
