AC Variable voltage supply (0 TO 1000 V, 11000 V, 66000 Volts),
All Electrical equipment are designed for specified supply voltage and the performance of the equipment is affected with voltage fluctuation. Both Low & High voltage are detrimental to the life/proper functioning of the equipment and cause the machine to run erratically or sometimes burning of the machine , thereby loosing production and the end result is economic loss of the many ways voltage fluctuations can be controlled, Rolling contact type voltage regulating units are the best. These units are custom built as per individual customers requirement and can be installed either indoor or outdoor to cater medium or high voltage supply fluctuations up to 33KVA with power handling capacity of 7000KVA. Rolling contact V.V.S./A.V.S. do not introduces any wave form distortion and are ideal for using in Chemical plants, Melting Furnaces, Air conditioning plants, Motor, Computer, Testing Laboratories etc.
