9907-186 | Woodward Reverse-Acting Engine Speed Governor

Woodward 9907-186 GS10 2301A Load Sharing and Speed Control Module

The 9907-186 (Model: 9907-186) is a high-precision reverse-acting electronic speed control and load sharing unit belonging to the Woodward 2301A/GS10 family. Engineered for complex power generation and marine propulsion systems, this module provides deterministic speed regulation for diesel engines, gas engines, and turbines. The 9907-186 (Part Number: 9907-186) is specifically designed for systems requiring a reverse-proportional response, where the actuator current decreases as speed error increases, ensuring fail-safe operation in specific prime mover configurations.

Adhering to strict Google E-E-A-T principles for industrial reliability, the 9907-186 (GS10: 9907-186) facilitates automatic isochronous load sharing among parallel generator sets. By monitoring the speed signal frequency and proportional load lines, it ensures that each engine in a multi-unit power plant carries its designated share of the total demand. This rack-mount module is encased in a rugged industrial housing, capable of maintaining high-frequency stability (up to 11,450 Hz) even in the high-vibration and extreme temperature environments typical of oil and gas compressor skids.
