Servo Stabilizer Aligarh

Electricity is an essential aspect of our daily lives, powering everything from tiny bulbs to large industrial machines and computer stations. However, frequent switches on and off of the power distribution line can lead to voltage fluctuation, adding or subtracting load, and causing damage to electronic and electrical equipment. In response to this problem, humans have developed various manual and automatic methods for controlling voltage fluctuation. The servo controlled voltage stabilizer is the most reliable method, which ensures a consistent power supply. With the help of this method, the servo voltage stabilizer was born and is widely accepted today. Research and development in the field of voltage fluctuation have resulted in innovative servo voltage stabilizers, which are the most accurate means for addressing the weaknesses in electrical equipment. The combination of high-quality components, electrical circuits, and control units ensures the quality of the servo voltage stabilizer.

How does it work?

Voltage stabilizers are widely used in both domestic and commercial settings to address the issue of voltage fluctuations and provide stable power supply. Electrical equipment can only perform efficiently and at maximum capacity when running at their rated voltage, which is where servo voltage stabilizers come in. By ensuring consistent input and output voltage, servo voltage stabilizers allow machinery to operate smoothly. Over and under voltage issues are common for electrical and electronic devices, leaving them vulnerable to serious damage. Stabilizers correct these voltage fluctuations to maintain the desired and consistent voltage level, ensuring the safety and longevity of the equipment.

The control circuit of a servo voltage stabilizer compares the output voltage with a built-in reference voltage and controls the servo motor accordingly. If there is a rise or fall in the voltage, the control circuit detects it and activates the servo motor. The amplifier and variable transformer work together to supply the buck boost transformer, which stabilizes the fluctuating voltage by correcting the fault through the comparison of the resultant error voltage and reference voltage, driving the servo motor.


Experienced engineers and management professionals are responsible for producing top-notch servo voltage stabilizers. Extensive and consistent research and development in the field of electrical energy and voltage fluctuation ensure that the product is safe, reliable, and highly accurate. The carefully chosen components used in manufacturing maintain a fast and high correction ratio against voltage fluctuations during operation. This level of dedication ensures efficient and trouble-free operation for both small and heavy electrical equipment. The entire unit is enclosed in a sheet metal cabinet with proper ventilation, which is sprayed with a lacquer finish paint. The assembly process results in a robust and sleek servo voltage stabilizer that is resistant to corrosion, guaranteeing a long product life cycle.
