Automatic voltage regulators (AVRs) keep the voltage going to your equipment steady when the supply drops or surges. They help protect refrigerators, aircon units, computers, audio equipment, pumps and small machines from low or unstable voltage, which is common at the end of long power lines.
How to choose a voltage regulator
- Capacity (VA or kVA): add up the wattage of the equipment you will connect and choose an AVR with spare capacity. Motors and compressors draw several times their running power when starting, so size up for refrigerators, aircons and pumps.
- Servo motor or relay type: servo motor AVRs like the Lotus SM series adjust smoothly and suit sensitive equipment. Relay types are compact and react quickly.
- Input range: check how low an input voltage the AVR can correct, especially in areas with frequent low voltage.
- Display and protection: a voltage display and built-in overload and delay protection make the AVR easier to monitor.

AVR, generator or both?
An AVR corrects unstable voltage, but it can't supply power during a brownout. For backup power, see generators and inverter generators, which are safer for electronics. You can also see the automatic voltage regulator collection, circuit breakers and other Chint electrical products.
