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.A Servo Stabilizer is a Servo motor controlled stabilization system that performs optimum voltage supply using a Buck\Boost transformer booster that captures voltage fluctuations from input and regulates current to the correct output.When the Servo stabilizer receives an input current, with fluctuating voltage, the microprocessors in the electronic circuitry triggers the Servo motor driver. This in turn activates the servo motor, which moves across the windings of the auto-transformer.

Servo is an electrical motor that is primarily an integral part of the stabilizer, which controls and stabilizes the output voltage supplied by the voltage stabilizer irrespective of the incoming voltage fed to it.
Accordingly, a few people call it as Servo Controlled Voltage Stabilizer while others go short by calling just as a Servo Stabilizer.

The Servo voltage stabilizer maintains the quantity of voltage in the power system, even in the case of voltage fluctuations. The control element basically converts the unregulated input to the regulated output. That is why it is called a voltage stabilizer.

Servo Stabilizers are an integral part of a production unit that uses electrical appliances and machinery. With servo stabilizers in place, the expensive machineries remain safe from any voltage fluctuations and also saves on excess electrical usage. To develop your understanding regarding the same, we look into the working principle of a servo voltage stabilizer today.

Compared to traditional transformers, Servo stabilizers employ a “Servo-mechanism” to control incoming voltage and regulating it to the prescribed voltage for an appliance.

Given below are the components of a servo stabilizer:

• Servo Motor
• Motor Driver or Relay
• Buck Boost transformer
