This 6GA2 492-1A automatic voltage regulator (AVR) is fully compatible with Siemens synchronous generator sets. Equipped with an aluminum finned heat sink, high-power wirewound discharge resistor and pre-wired harness, it precisely adjusts excitation current to stabilize generator output voltage, with built-in overcurrent, overvoltage and underfrequency protection. Each unit comes with a complete 12-pin pluggable terminal connector for easy field wiring, widely applied to marine main and emergency diesel generator systems.
