Three Phase Oil Cooled Servo Voltage Stabilizer

Three Phase Oil Cooled Servo Voltage Stabilizer(3-2000)KVA

We are manufacturer, supplier and Exporter of wide spectrum of Servo Voltage Stabilizer and Voltage Regulators, which are used with various electrical and electronic applications.

We offer high grade Three Phase Air Cooled Servo Voltage Stabilizer, which are impeccably designed by us in our sophisticated infrastructure using latest technology. These types of Voltage Stabilizer are extensively used to control the voltage fluctuation with solid state electronic circuitry. Air cooled stabilizers and regulators developed by us are automatic line voltage corrector, which use synchronous motor in close loop control. We offer these three phase stabilizers & regulators at very competitive prices.

Our Three Phase Air Cooled Servo Voltage Stabilizerhave been designed to give a constant output voltage for single applications with stability +- % of the efficiency has been maintained a s high as 95 % or more. We offer various types of automatic voltage controller and servo stabilizers which includes balanced type and unbalanced type automatic voltage controller and regulators.

Three Phase Oil Cooled Servo Voltage Stabilizer

We offer you these 1 phase servo stabilizers in both Oil cooled and air cooled design. These oil cooled stabilizers are used in several industrial, commercial and domestic applications. These types of industrial automatic voltage controller and servo type voltage regulators are designed for precise control of output voltage that significantly increases the life of appliances and machine connected through it. These servo controlled stabilizers also reduces breakdown and the cost maintenance. These oil type voltage regulators and controllers significantly control high or low input voltage to prevent electrical instruments from damaging.
