The POWERGUARD  offers the most cost effective and efficient way to ensure a stable, undistorted mains supply for the vast majority of applications.

Based on the proven electronic servo design, a double wound transformer has its secondary winding connected between the incoming AC supply and the load, with the primary winding voltage controlled by a motor-driven variable auto transformer. A solid-state servo amplifier continuously monitors the output voltage of the stabiliser, and any error voltage is amplified to operate the servomotor of the variable transformer, driving its brush-gear to a point where it is injecting a voltage that will correct the supply voltage by adding or subtracting from it.

Over several  ratings from 1kVA to 1000kVA, single or three phase, incorporating full transient spike and noise suppression if required. Available with a wide selection of input voltage ranges from ±13% to ±40%

All of our products are based on our unique experience gained over thirty five years.

All our stabilisers are manufactured under strict quality controlled procedures approved to ISO 9001:2008.

Every stabiliser  complies with the IS-9815 to ensure that the quality and reliability of our products can be assured. We can confidently claim to have manufactured hundreds of AC Voltage Stabilisers and are  in service in some of the toughest environments .

Key Features

·         High speed of response

·         Low internal impedance

Capable of sustaining high surge currents.

·         Efficiency better than 98% with up to 99.5% on higher models.

·   Modular start of art design and assembly.

·      Latest  LCD micro controller with clock

·         Soft-start ensures low output voltage at the moment of switching on.

·         Soft-stop dampens the force of impact when the variable transformer brush gear reaches the end stop.

·         Certified by ETDC & MSME FOR CONFORMATION AS PER IS9815.

·         Spike Suppression. Metal oxide transient voltage suppression is fitted as standard. Additional protection can be provided to attenuate spikes and noise down to harmless levels

·         Lightning Arrestors. Can be provided to protect the stabiliser and the load from the harmful effects of induced lightning strikes to the incoming supply distribution network. IEC 61643-1 Class ll / Imax 40kA.
