Product Description

The 9905-068 is a core control module of the Woodward 2301A Series, developed by Woodward, Inc. for speed governing and load sharing in generator sets.

This controller maintains constant system frequency and enables proportional kW load distribution when multiple generators operate in parallel or are connected to a utility grid. It regulates fuel, steam, or gas flow via actuator control signals to maintain stable prime mover speed and electrical output.

The 9905-068 uses analog control architecture with potentiometer-based field adjustments, allowing engineers to tune gain, reset, and compensation parameters without specialized software tools. Its fast analog response and rugged design make it suitable for marine propulsion, industrial power generation, and remote power systems.

FAQ

Can it operate on 115 VAC systems?
No. This is a DC-powered module (20–40 VDC). An external 24 VDC supply is required.

Can it share load across different engine types?
Yes. As long as compatible Woodward load-sharing controllers are used.

What actuators are supported?
Compatible with proportional Woodward actuators such as EPG, 723, and EG series devices.
