Servo Voltage Stabiliser Three Phase - Aircooled

Servo Voltage Stabiliser:

Three Phase - Aircooled 3 kVA - 150 kVA.

VERTEX Servo Voltage Stabiliser uses an intelligent Microcontroller (DSP) based control system to protect industrial machinery from damage caused due to high & low voltage fluctuations. Essentially, it prolongs the useful life and reliability of critical machinery. VERTEX is one of the pioneers to develop and introduce a Microcontroller (DSP) based control system in the Servo Stabiliser Industry. Three Phase aircooled voltage stabilisers consist of three single phase units connected in star. The voltage sensing & correction is done in each phase independently with respect to the neutral, this is the reason why they are also called unbalanced type voltage stabilisers.
