AVR stands for "Automatic Voltage Regulator," a device that maintains a constant voltage level in electrical systems. It ensures that the voltage remains stable, protecting sensitive equipment from fluctuations that could cause damage. By automatically adjusting the output voltage, an AVR helps to improve the reliability and efficiency of power supply systems. In addition to its use in power generation, AVR technology is also found in generators and uninterruptible power supplies (UPS). These devices are crucial in various settings, from homes to industrial facilities, where consistent power is essential for the operation of computers, machinery, and other electronic devices.
