voltage fluctuation In the real world power line voltage occurs frequently especially in industrial area. Every electrical equipments and devices do have a working voltage limit/tolerance. Some equipment are build to tolerate ±10% of nominal voltage while others ±5% or less depending on sensitivity.
effects The correct operation of electrical and electronic equipment depends on the voltage accuracy and stability. In the event of long time over voltage, it will lead to damage of the equipment; while long time under voltage will cause malfunction and computation errors of the electrical & electronic equipment.
solutions Installing QPS Automatic Voltage Stabilizer (AVS) or power line conditioner will ensure the continuity and
quality of production.
Input voltage variation from:
Single Phase: 230VAC ±12%
Three Phase: 415VAC ±12% + Neutral (3 phase 4 wire)
– excellent output voltage accuracy of within ±1.5% set value.
– regulation correction time approximately 0.05 ~ 0.07 sec per volt.
– minimum maintenance due to its simplicity in design.
– easy installation.
– tailor made to special voltages and configuration for example, three phase voltage without neutral or for outdoor configurations.
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 to the supply system. QPS Three phase Automatic Volltage Stabilizer also designed to cater for unbalanced load. This made possible with its independent phase monitoring system.
QPS Automatic Voltage Stabilizer offer high quality performance at competitive prices. They solve voltage unstable problems and increase productivity.
power line conditioner QPS power line conditioner (PLC) is a AVS with the inclusion of a shielded isolation transformer.
