EFC 4914090 Generator Speed Controller Unit Electronic Engine Governor Control Compatible with NT855 Engine 24V Speed Control Board

EFC 4914090 Generator Speed Controller Unit Electronic Engine Governor Control Compatible with NT855 Engine 24V Speed Control Board The 4914090 electronic governor is the core of the fuel system for Cummins NT855 generator sets. By receiving speed signals from the magnetic pickup, it dynamically adjusts the fuel supply to the actuator, maintaining the engine at the preset speed under varying loads. This controller features an ultra-fast dynamic response, quickly restoring speed during sudden load changes to reduce voltage fluctuations and ensure power quality. Technical Parameters / Technical Data: Operating Voltage: 24V DC Steady State Band: ±0.25% Ambient Humidity: Up to 95% Compatibility: NT855 and related series
