Three Phase Servo Controlled Voltage Regulator


Continuous stable supply of A.C. Power is the life line of any sophisticated electronic system. Performance of any electrical equipment/instrument is optimum at its rated voltage, Under-voltage & Over-voltage produce harmful effect.

Under-voltage generally reduces efficiency, whereas Over-Voltage shortens the life. Power SPIKES, accidental OR from the Electricity Boards, can waste very valuable time and corrupt the valuable data fed in. Also a very low voltage can force the system to shut down.

PACE Automatic voltage regulating Devices / Stabilizers, an excellent remedy for the problems met with, in ensuring optimum performance and in safe-guarding expensive equipments under conditions of wide line voltage fluctuations incorporating latest in integrated circulatory & solid state technology.

Three Phase System
We offer two types of three phase systems.

1. Un-Balanced load
2. Balanced load.

In situations where the three phase-to-neutral voltage vary without equality to each other, each phase will have to be corrected independently and this will require three single phase stabilizers connected in star, one for each phase between neutral an phase wire. However in standard BALANCED LOAD versions, only one of the three phase is monitored for error and necessary correction is effective for all three phase voltages However, a switch is provided to select any one of the three phase for monitoring. The voltmeter also has a 6 position rotary switch that shows input and output voltages of any of the three phases.
