Three Phase Aircooled Servo Stabilisers consists of three single phase units connected in star. The voltage sensing & correction is done in each phase independently with respect to the neutral, also called as unbalanced type voltage stabilisers. These stabilisers are used for various kinds of machinery like CNC, Textile, CT Scans, Printing, Packaging, Freezers, etc. RAMESHWAR Stabiliser uses a Microcontroller (DSP) control system to provide a steady voltage and also protects the machinery from under/over voltage, overload, single phasing and phase reversal conditions.oltage fluctuation is a common phenomenon in every part of the country. The industrial units running round the clock, usually face the problem of low and high voltage. 90% of industrial load motors . Electric motors draw considerably high current at low & high voltage.
