Introduction

In today’s world, electricity is the backbone of every industrial, commercial, and residential operation. However, power fluctuations are a common problem that can damage sensitive equipment and reduce their lifespan. To prevent such issues, Automatic Voltage Regulators (AVRs) are used. An AVR ensures a stable voltage supply to protect your valuable electrical and electronic devices.

What is an Automatic Voltage Regulator (AVR)?

An Automatic Voltage Regulator is an electrical device that automatically maintains a constant output voltage level, regardless of fluctuations in the input voltage. It detects over-voltage and under-voltage conditions and adjusts them to provide a stable and safe power supply.

AVRs are essential for protecting devices like computers, lifts, medical instruments, industrial machinery, and telecommunications systems from voltage instability.
