POTENTIAL 20W
The Woodward Load Sharing Module 9907-173 Rev B is a precision control component designed to balance and distribute electrical load across multiple generators operating in parallel. As a core element within a marine control system, this module regulates governor outputs to ensure stable load sharing between gensets, preventing overloading of individual units and maintaining grid stability aboard the vessel. Reliable load sharing is critical to safe power management at sea, directly supporting propulsion, hotel loads, and essential safety systems.
Key Features
✓ Designed for load sharing control across parallel-connected generators, coordinating governor response to maintain balanced kW distribution.
✓ Wide input voltage range of 100–240 VAC with frequency compatibility across 50–400 Hz and a power potential of 20W, as stated in the original product data.
✓ Compatible with Woodward governor and control systems typical to marine power management panels; exact system compatibility subject to confirmation based on installation configuration.
✓ Intended for installation within control panels or enclosures in machinery spaces; mounting location and environmental requirements depend on vessel layout and applicable standards.
✓ Replacement of this module should be undertaken with reference to the existing panel wiring, governor model, and system revision level to ensure correct interfacing — subject to confirmation.
Marine Applications
✓ Diesel-electric vessels requiring parallel generator operation with precise active load distribution across the switchboard.
✓ Engine control rooms on cargo ships, tankers, and offshore support vessels where generator synchronisation and load balance are continuously managed.
✓ Power management systems on ferries and passenger vessels where stable onboard electrical supply is operationally critical.
✓ Genset control panels on platform supply vessels (PSVs) and anchor handling tug supply (AHTS) vessels operating dynamic positioning systems.
✓ Retrofit and upgrade projects replacing obsolete load sharing modules within existing Woodward-based marine governor control architectures.
Why Marine Engineers Choose
Woodward is a globally recognised name in governor and power control technology, and the 9907-173 module reflects the brand’s commitment to precise, reliable load management. Marine engineers select this module for its compatibility within established Woodward control architectures and its role in maintaining the electrical stability that vessel operations depend upon.
Ideal For
Cargo vessels, tankers, offshore support vessels, ferries, passenger ships, and any commercial or industrial marine platform operating parallel generator sets within a Woodward-based power management or engine control system.
Technical Support & Compliance
Technical assistance is available to support troubleshooting, testing, commissioning, and integration of this module within existing onboard control systems. Retrofit and upgrade guidance can also be provided where this unit is being installed as a replacement within an existing Woodward governor or load sharing architecture. Repair assessment is available subject to inspection. All compatibility, interfacing, and compliance confirmations are subject to review of the specific installation. To confirm suitability, buyers are advised to share nameplate photographs, existing part numbers, panel drawings or schematics, governor model and software version, vessel name, IMO number, and a clear description of the intended scope of work.
