A 2kVA Automatic Voltage Regulator (AVR) is a single-phase electrical device designed to deliver a stable output voltage (typically 220V or 230V) despite wide input fluctuations. Its 2 Kilovolt-Ampere capacity makes it suitable for protecting moderate loads in homes and small offices, such as televisions, refrigerators, computers, and small machinery.
The AVR works automatically, often using a servo motor or relay-based system, to correct voltage sags, spikes, and surges. Key features usually include a wide input voltage range (e.g., 100V−260V AC), over/under-voltage protection, overload safeguarding, and often a time-delay function for safe appliance restart after a power outage. It is essential for extending the lifespan and ensuring the reliable operation of sensitive electronics.
