5kva Ac Automatic Voltage Regulator Avr

A 5kVA AC Automatic Voltage Regulator (AVR) is a crucial device that stabilizes electrical output against fluctuations. Rated for 5000 Volt-Amperes, it's commonly a single-phase unit, using either servo motor or relay technology to maintain a precise, constant output voltage (e.g., 220V±3%) despite a wide input range (e.g., 140V−260V). Its primary function is to protect sensitive equipment like refrigerators, computers, TVs, and medical devices from damage caused by low voltage (brownouts) or high voltage surges. Essential features include overload/short-circuit protection and a time-delay safety cycle.
