The Woodward Load Sharing Module (part number 9907-838) is a precision control component designed to manage and balance electrical load distribution across multiple generators or power sources aboard marine vessels. As a core element of the Marine Control System, this module ensures that generating sets operate in synchronised harmony, preventing overload on individual units and optimising fuel consumption across the power plant. Its role is critical to maintaining stable onboard power during manoeuvring, port operations, and open-sea passages.
Key Features
✓ Operates on 24VDC with pulse-width modulation (PWM) output, enabling precise and responsive load regulation across connected generating sets.
✓ Wide-range AC supply input of 100–240VAC at 50–400Hz with a 10W power consumption rating, making it compatible with varied shipboard power architectures.
✓ Carries CE marking and UL/CUL certification, confirming compliance with international safety and electromagnetic compatibility standards relevant to marine and industrial installations.
✓ Designed for integration within Woodward governor and power management control panels; compatibility with specific systems should be confirmed against vessel configuration and software version.
✓ Suitable for installation within control cabinets in engine rooms or power management enclosures; replacement or retrofit applications should be verified against existing wiring diagrams and system drawings prior to installation.
Marine Applications
✓ Parallel generator load sharing on merchant vessels, tankers, and bulk carriers operating multiple generating sets across extended voyages.
✓ Power management systems aboard offshore support vessels, platform supply vessels, and anchor handlers where dynamic load balancing is critical to operational safety.
✓ Engine room automation systems on cruise ships, ferries, and RoPax vessels requiring continuous and stable load distribution across hotel and propulsion loads.
✓ Integration within Woodward-based governor control panels on naval auxiliaries, research vessels, and government-operated craft with regulated power plant requirements.
✓ Retrofit and upgrade projects on ageing tonnage where existing load sharing modules require like-for-like replacement to restore compliant power management functionality.
Why Marine Engineers Choose
The Woodward 9907-838 Load Sharing Module is trusted by marine engineers for its robust build quality, wide power supply tolerance, and certified compliance — making it a dependable choice for maintaining stable generator synchronisation and load balance in demanding shipboard environments.
Ideal For
Merchant vessels, offshore support vessels, ferries, cruise ships, research vessels, naval auxiliaries, and any commercial or industrial marine application operating Woodward-based power management and governor control systems.
Technical Support & Compliance
Remote troubleshooting guidance, onboard commissioning support, functional testing assistance, and integration advice are available to help ensure correct installation and operation of this module within your existing power management system. Retrofit and upgrade suitability is subject to confirmation based on your vessel’s control architecture and software version. To confirm compatibility, buyers are encouraged to share nameplate photographs, existing part numbers or revision codes, system schematic drawings, the generator control panel model and firmware version, and vessel name or IMO number where applicable. All compatibility assessments are subject to confirmation upon review of the supplied technical documentation.
