Servo Voltage Stabilizers: - Air-Cooled vs Oil-Cooled

To protect your critical types of equipment Nantech power systems Pvt.Ltd. the best servo voltage stabilizer dealers provide one of the best voltage stabilizers in Chennai city. This city is already advanced in technologies providing the futuristic level of hardware designs. If you are looking for servo voltage stabilizers your search ends here.


Voltage stabilizers are used to stabilize or regulate the voltage if the voltage is fluctuating over a given range. The main purpose of stabilizers is to provide a constant voltage to load or appliances.Servo Stabilizer is a Servo motor driven stabilization system that performs optimum voltage supply.

Servo stabilizer is an electromechanical device therefore its voltage correction speed is slower than static voltage stabilizer.

Following are the two types of servo voltage stabilizers

  • Air-cooled Servo Voltage Stabilizers
  • Oil-cooled Servo Voltage Stabilizers

Air-cooled Servo Voltage Stabilizers:

Air-cooled Servo Voltage Stabilizers are very much useful for various electrical as well as electronic applications.The servo stabilization mechanism with air-cooling means efficiently ensures optimumvoltages.This stabilizer includes a transformer and a power control circuit for controlling output AC voltage. The negative feedback circuit controls the voltage or power automatically and regulates it to a level that’s set or required. The most effective part is that within the entire operation, the voltage regulator doesn’t require any manual interruption, it functions automatically.

Oil-cooled Servo Voltage Stabilizers: -

Oil-cooled have inherently higher short-time or sustained overload capacity as compared to Air-cooled types. The main difference between oil-cooled and air-cooled stabilizers is the capacity of oil-cooled stabilizers are for higher capacity. These are used in places where there is a high frequency of fluctuating voltage in the power supply. Anoil-cooled stabilizer guarantees that the fluctuation in the power supply does not affect the electronic or electricaltypes of equipment.
