Automatic Voltage Regulator
In StockAn Automatic Voltage Regulator (AVR) is an intelligent electronic device designed to automatically maintain a constant and stable output voltage level for electrical equipment. It continuously monitors the input voltage and instantly corrects any fluctuations—whether over-voltage or under-voltage—ensuring reliable and safe power delivery.
AVRs are essential in protecting sensitive devices such as generators, computers, medical instruments, CNC machines, and industrial control systems from power instability. Built with microprocessor-based control circuits, it offers fast correction speed, high accuracy, and energy-efficient operation. It also includes advanced features like overload protection, phase failure safety, short circuit prevention, and digital voltage display for real-time monitoring.
