Brands Servo Stabilizer


We are suppliers of Air cooled and Oil cooled Servo Controlled Voltage Stabilizer which are used for various electrical and electronics application.

We offer high grade Air Cooled Servo Voltage Stabilizer which are designed by us using latest technology. Our Stabilizers are extensively used to control any critical equipment which is affected by voltage fluctuation with latest electronic circuitry.

Our designs are selected by premium quality raw material and are known for low power consumption, heat reducing capacity and trouble free operation and also designed to give a constant output for the application with stability 98% efficiency and more.

Three Phase Air-cooled Servo Stabilizers 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 stabilizers. These stabilizers are used for various kinds of machinery like CNC, Textile, CT Scans, Printing, Packaging, Freezers, etc. Our Stabilizer are designed with 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.

Custom Designed: Stabilizers of more than 200KVA are also available with wider / shorter input voltage range & also with special output voltage, as per customer requirements.
