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 .
