Product Description

AC mains voltage fluctuations are a common phenomenon in power supply system. Such fluctuations may result into erratic behavior, malfunction or even break down leading to expensive repairs, production loss and missed commitments.

Servo Voltage Stabilisers are designed to ensure that their output voltage remain constant irrespective of the voltage swings in the incoming power supply.

Their high efficiency and the ability to withstand instant load variations make them an ideal choice for protection of expensive and sensitive equipment.
