Woodward 9905-096 Automatic Generator Loading Control Module

The Woodward 9905-096 Automatic Generator Loading Control Module is a precision-engineered device designed to manage the automatic loading and unloading of generators in power generation systems. This control module plays a critical role in systems where synchronized operation, load stability, and fuel efficiency are paramount. It ensures that generators are brought online or taken offline smoothly, without disrupting power quality or causing overload conditions.

Part of Woodward’s well-established 9905 series, the 9905-096 module is especially suitable for applications requiring continuous operation, quick response to load changes, and minimal human intervention. The unit automates decisions about when to connect or disconnect generators based on load demand, frequency regulation, and system conditions, making it essential in multi-generator environments.

Housed in a robust enclosure, the 9905-096 is built to withstand harsh operating conditions found in industrial, marine, and utility settings. It seamlessly interfaces with governors, synchronizers, and other control equipment, allowing full integration into modern or legacy generator control systems.
