Woodward 9905‑376 2301A Speed & Load Sharing Control Unit
The Woodward 9905‑376 is a 2301A series electronic speed and load‑sharing control unit for diesel and gas generator sets. It receives speed sensor signals, outputs drive signals to fuel actuators, realizing precise engine speed regulation and load distribution among multiple parallel‑running generator units.
This analog governor controller features adjustable speed droop, stable dynamic response and panel potentiometer settings. It is a critical spare component for overhaul and retrofitting of marine, industrial and emergency backup generator control cabinets.
