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

Voltage fluctuation is common in any electrical supply system. Continuous variation of loads and extension of power lines are the main factors which contribute to the above problem. In spite of all efforts done by the utility companies, they are still unable to provide a constant supply to the users yet.

However, sophisticated equipment requires stable voltage supply in order for them to perform accurately, such as Transmissions & Tele-communications equipment, Laboratory and Test equipment, Computer Numerical Control (CNC) equipment etc.


Voltage fluctuation can cause testing equipment to give inaccurate data, computerized or automatic machines to produce defective parts, security system malfunction, inconsistency of motor speed etc. These effects are very costly too in terms of downtime and rejects.


QPS  Single Phase and Three Phase Servo - Motor Automatic Voltage Stabilizers (AVS) are capable of eliminating the above problems with ease. They are designed to cater for:-

  • Input voltage variation from: Three Phase : 415V ± 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 possible.

QPS Three Phase Automatic Voltage Stabilizers are also designed to cater for unbalanced load. This is made possible with its independent phase monitoring system.

QPS Automatic Voltage Stabilizers offer high quality performance at competitive prices. They are created to solved problems and increase productivity.
