Servo Stabilizers Manufacturers

Servo Stabilizers play a crucial role in protecting delicate equipment. They run on servo motors, which rotate in both clockwise and anticlockwise directions to regulate the voltage fluctuation. Servo stabilizers deliver instantaneous stabilization as they take only 50 milliseconds to 5 seconds with a voltage correction speed of 100 volts per second.

EVR Power is the best servo stabilizer manufacturer in India, and they build servo stabilizers with high efficiency and low maintenance thus reducing your operating costs.   


Why do we need a Servo Stabilizer?

In today’s modern world, Voltage stabilizers are an integral need from Industrial operations to household needs for electrical stability problems. The major purpose of the voltage stabilizer is to convert unregulated input electrical signals into regulated output signals.

The different types of voltage stabilizers are: 

  • Relay type voltage stabilizer
  • Static voltage stabilizers and
  • Servo controlled voltage stabilizer.

Among the three, Servo voltage stabilizers serve the purpose of providing steady output voltage utilizing built-in servo motors. Servo stabilizers are also called automatic voltage regulators as the microprocessors present inside the electronic circuit unit actuates the servo motors when it receives a fluctuating input voltage signal.  

The servo motors move across the autotransformer and regulate the required output voltage which is transferred to the buck-boost transformer (DC to DC converter for step-up or step-down purposes).

What are the different types of Servo Stabilizer?

  • Single Phase Servo Based Voltage Stabilizers
  • Three Phase Balanced type Servo Based Voltage Stabilizers
  • Three Phase Unbalanced type Servo Based Voltage Stabilizers

The single-phase servo voltage stabilizers comprise servo motors linked with autotransformers and transfer the regulated voltage to the buck-boost transformer working on the principle discussed above. In the case of a three-phase balanced type, a servo motor is coupled with three autotransformers providing modulated steady output voltage instantaneously. 

The unbalanced type holds three different servo motors interfaced with individual autotransformers providing effective output voltage. Compared to other voltage stabilizers, servo stabilizers provide precise high voltage stabilization, rapid functioning, high reliability and serve for domestic and industrial electrical appliances.

Applications of a Servo Stabilizer

  • A wide variety of applications such as industrial, domestic, commercial systems can be protected using EVR power Servo voltage stabilizers. Servo stabilizers provide safeguarding solutions for electronic devices protecting their electrical/electronic components from serious damage.

  • The input signal fluctuation causes heat energy causing premature failure to the sensitive circuit board and microprocessor chips. The recurrence of fluctuating signals causes permanent damage to the electric and electronic system. Therefore, Servo stabilizers provide a stable flow of input voltage balanced according to the electric system and prevent overheating. The effective performance keeps the electrical system in ambient conditions providing longevity.

  • In recent times, the rapid advancement of the Information technology revolution requires an uninterrupted stable power supply for the use of high computing power in large Data centres and IT-based tech parks to avoid several factors such as network issues, data fragmentation and server problems. Servo stabilizer provides 100 % protection to the overall electrical devices supplying precisely engineered output power supply.

  • Also, real-time scenarios such as live broadcasting studios, concerts and massive live events require standardized input voltage to avoid critical failures for up and down streaming of data. Automatic voltage regulators can handle heavy voltage fluctuations and provide long-hour service for outdoor conditions. Therefore, EVR power is a one-stop solution for all your transformer needs delivering products with cutting edge technology and further providing outstanding services round the clock for our valuable clients.

1. What is the purpose of the Servo Stabilizer?

A Servo Stabilizer is a motor-powered apparatus that helps stabilize familiar household appliances, like refrigerators and air conditioners. It does this by means of a process called voltage boost technology using a Buck\Boost transformer. This prevents electrical power volatilities from causing damage to your appliances.

2. How do Servo Stabilizer work?

The mechanics of a servo voltage stabilizer operate by ensuring that the input voltage is always constant and no matter the output load current. The electronic circuitry within the device sends an analogue signal to the oscillator along with a digital pattern which in turn sends signals to the Motor Driver and subsequently activates the Servo Motor, driving across the windings of an autotransformer – these connections make up a part of an oscillator which changes its frequency according to incoming signals from microprocessors.

3. What is the difference between Servo Stabilizer and Voltage Stabilizer?

As the Voltage stabilizer doesn’t contain any moving parts, it is a pure electric circuit that makes up the corrections in voltages. On the other hand, the Servo Stabilizer uses a servomotor controlled stabilization system that helps make voltage corrections.
