Oil Cooled Servo Stablizer

home / Oil Cooled Servo Stablizer


Voltage Stabilizers are classified into Single Phase and Three Phase Servo Voltage Stabilizers. However, the major components of a Servo Voltage Stabilizer include a motorized variable transformer, controller, and a buck-boost transformer.

With THE HIGH-QUAILITY MATERIAL used in the manufacturing process, Dhruvi Enterprise is marked as the Best Three Phase Voltage Stabilizer Manufacturer in Gujarat. We aim to provide the devices for the smooth performance of electric-electronics power devices, lower maintenance, and high productivity. Caring the customer need is our motto.

3 Phase Servo Voltage Stabilizer continually monitors the output voltage and controls the input voltage variations by movements of a motor. This stabilizer is manufactured under the strict inspection of expert professionals using high-quality materials and components.

Servo stabilizer is a system, which provides stable Alternate Current (AC) output voltage where the input power supply voltage changes drastically. It protects the costly equipment from high and low voltage problems.
