AVR20 automatic voltage excitation regulator for generator sets Easy installation on generator set equipment. The AVR20 is designed for straightforward wiring and mounting. performance under strict standards. This regulator delivers reliable automatic voltage regulation to improve power quality. Stable voltage across a range of operating conditions. It handles startup with no voltage output, low voltage, overvoltage, unstable voltage, large voltage swings, normal noload voltage, and voltage drop under load, helping to keep output steady. Low frequency protection and fourwire configuration. Built for reliable operation and safe, consistent regulation. Broad compatibility and dependable performance. Suitable for a wide range of generator sets and AVR wiring configurations. Practical benefits. Improves voltage stability, protects connected equipment, reduces wear from voltage fluctuations, and enhances overall generator control. Use scenarios Home backup power systems: ensures stable voltage during outages and fluctuating loads. Industrial generator sets: maintains consistent output to protect motors and sensitive machinery. Remote sites and construction projects: provides reliable power when loads vary and remote access is limited.
