Servo Control Voltage Stabilizers by Rishab

A servo controlled voltage stabilizer (SCVS) is a regulator designed with microcontroller to automatically maintain constant voltage level. In most industries, a minor fluctuation in voltage can cause the connected equipment to malfunction or breakdown. The basic use of SCVS is to control fluctuation and to provide a constant output Voltage with +/- 1% accuracy.

SCVS is supplied in following types according to its input and output Supply as:

3Phase to 3Phase, 3Phase to 1Phase, 1Phase to 1Phase

3Phase to 3Phase SCVS

3Phase to 1Phase SCVS

1Phase to 1Phase SCVS

3Phase to 3Phase SCVS

These SCVS have 3Phase input supply with 3 / 4 Wire Configuration and provides 3 Phase Constant Voltage Output with 4 Wire Configuration.
