Woodward 9905-363
Compact integrated microprocessor electronic governor controller, specially designed for small and medium bore diesel engines and gas engines. It integrates speed closed-loop regulation, load dynamic adjustment, start-up fuel limit and fault protection logic into one unit. Adopt high-speed microprocessor core, built-in mature PID regulation algorithm, with stable dynamic regulation performance and low speed fluctuation rate. The whole machine is sealed and dustproof, suitable for engine room high temperature, oil mist and vibration harsh environment, can independently complete single unit speed regulation and parallel operation load distribution control.
