Product Description
Woodward 9907-1320 is an electronic load sharing and speed governor controller of Woodward 2301A series, a classic analog governor for generator sets. It supports Isochronous and Droop control modes, featuring multi-unit load sharing, start fuel limit, acceleration/deceleration ramp and overspeed protection. It receives MPU magnetic pickup speed signal and outputs 0–200mA current to drive fuel actuator without actuator position feedback. Onboard adjustable potentiometers enable convenient field tuning. Forward / reverse acting configuration available for diesel and gas engine generator sets. This model is discontinued by original manufacturer and supplied as spare part for power plant control system maintenance.

Product Application
It is applied for speed stabilization of single diesel or gas generator set and balanced load distribution for paralleled generator units. The controller measures prime mover real-time speed, compares it with setpoint and outputs control current to fuel actuator for fuel adjustment. It supports generator paralleling, decoupling, soft loading and unloading to prevent overspeed and overload. Widely used in oil & gas field power stations, captive power plants, marine power stations and emergency backup generators. It is essential governor spare part for legacy paralleling power generation control systems.
