Automatic Voltage Stabilizer (V-Series) - Single Phase V-Series Automatic Voltage Stabilizer

QPS  Single Phase Servo- Motor Automatic Voltage Stabilizers (AVS) are designed to cater for:-

  • Input voltage variation from: Single Phase : 230V ± 12%;
  • Excellent output voltage accuracy of within ±1.5% set value.
  • Regulation response time approximately 0.05 ~ 0.07 sec per volt.
  • Minimum maintenance due to its simplicity in design.
  • Easy installation.
  • Tailor make to special voltages and configuration are available.

QPS   Servo - Motor Automatic Voltage Stabilizer provides a continuous monitoring of the output voltage (true RMS sensing) by means of an electronic Control Circuit that compares the instantaneous output voltage with the set value. When changes are detected due to fluctuation of supply voltage or sudden changes in load, an electrical signal will be transmitted to the servo - motor which is coupled onto the brush gear of the variable transformer, causes the brush gear to rotate until the appropriate voltage, is restored. This method of stabilization does not create interference or harmonic in the supply system.
