The Woodward 9907-1200 is a single-channel electronic governor that forms part of Woodward's PSG (Precision Speed Governor) series, designed to provide accurate speed regulation for various prime movers including diesel engines, gas turbines, and steam turbines. This unit combines digital electronic control with hydraulic actuation, featuring advanced microprocessor-based technology for precise speed sensing and control algorithms. The governor maintains stable operation during load changes, startups, and shutdowns by continuously monitoring speed parameters and adjusting hydraulic pressure to the actuator accordingly. It offers features such as adjustable speed droop, isochronous load sharing capability, and comprehensive protection functions including overspeed detection. The 9907-1200 is designed for easy integration into both new installations and existing PSG-based systems, maintaining backward compatibility with Woodward's hydraulic components. Its rugged construction ensures reliable performance in demanding environments such as power generation plants, marine propulsion systems, and industrial applications. The governor represents Woodward's expertise in blending traditional hydraulic reliability with modern electronic precision for optimal control performance.
