AVR stands for Automatic Voltage Regulator, which is a device that regulates the voltage of an electrical system to provide a stable output voltage. Here are some short features of AVR:

• Voltage regulation: AVR devices are designed to regulate the voltage of an electrical system, providing a stable output voltage despite fluctuations in the incoming voltage.
• Automatic adjustment: They automatically adjust the output voltage to match the input voltage, ensuring a constant and stable output.
• Protection against power surges and spikes: AVR devices protect connected equipment from power surges and spikes, which can cause damage or data loss.
