Automatic Voltage Regulators & Stabilizers
Reliable power with advanced voltage regulators (AVR & AVS)
If you work in industries with electrical equipment, understanding the market for automatic voltage regulators is essential. Our AVRs provide continuous voltage and reliable power to protect your laboratory equipment, industrial machines and medical apparatus from detrimental low and high voltage fluctuations.
Servo AVR — 1kVA to 3000kVA
An Automatic Voltage Regulator (AVR) is an essential component in many electrical applications and is designed to meet the needs of different types of electrical systems. Whether you are using a small or large electrical system, AVR helps to maintain a constant voltage level, reduce the risk of device failure and increase the lifespan of electrical devices.
Our energy solutions team offers Automatic Voltage Regulator (AVR) delivery, installation and maintenance services countrywide. Servo AVRs consist of a Smart DSP Microprocessor Controller that supervises AVR operation and efficiency, a Variac, a servo motor that controls the Variac, an electronic multimeter card that controls this motor, and a booster transformer for voltage regulation.

Servo vs. Static
Which AVR type suits you?
Servo AVRs
Control fluctuating voltages by rotating the servo motor clockwise and anticlockwise, assisted by a buck-boost and a variable transformer.
- 1ph/1ph and 3ph/3ph configurations
- Independent line regulation
- Microprocessor controlled
- Wide input voltage range 155Vac–498Vac
- Stable output 400Vac/230Vac or 415Vac/240Vac
- Digital Signal Processing for accurate, fast response
- Long-term and short-term overload protection
- Air-cooled operation
- 2-year warranty
Ideal for domestic use, banking, telecoms, buildings, electrical machine protection, light industrial applications and precision measurement instruments.
Static AVRs
Lack movable parts and control the voltage using microprocessors and buck-boost transformers.
- No moving parts — reduced wear and low maintenance
- Microprocessor-controlled buck-boost regulation
- Fast response to voltage transients
- Suitable for sensitive electronics and IT loads

Sizing guide
How to choose the best-sized AVR
When selecting an automatic voltage regulator, consider the following factors:
Wattage of Energy Required
Determine the energy needed to operate your equipment.
Extent of Voltage Fluctuations
Assess the voltage fluctuations around your installation area.
Type and Working Scope
Understand the type and operational scope of the voltage regulator.
Once you have the right-sized automatic voltage regulator, ensure the following:
Confirm Power Rating
Check the power rating of your equipment from the nameplate or user manual.
Add a Safety Margin
Include a safety margin in the regulator rating to accommodate more devices.
Measure in kVA
AVRs are measured in kVA — calculate wattage by multiplying voltage by the maximum rated current.
