WOODWARD
PART NO: 9907-028
SPM-A SYNCHRONIZER MODULE
REV: E
CAGE: 31361
The Woodward SPM-A Synchronizer Module (part number 9907-028, Revision E) is a dedicated automatic synchronizing unit designed to manage and control the process of bringing a generator into phase, frequency, and voltage alignment with a live busbar prior to paralleling. As a core component within a marine control system, it plays a critical role in ensuring safe, seamless generator synchronization aboard vessels where uninterrupted power availability is essential to propulsion, navigation, and safety operations. Reliable synchronization control helps prevent damaging power surges and protects both generating sets and connected loads.
Key Features
✓ Designed to perform automatic synchronization of AC generators, monitoring and correcting phase angle, frequency, and voltage match before closing the breaker — typical of the SPM-A module architecture.
✓ Specific voltage ratings, response times, and output configurations are subject to confirmation based on the installed system; buyers should verify compatibility against their existing power management panel or governor control setup.
✓ Compatible with Woodward governor and power management systems as part of an integrated marine electrical control architecture; exact panel and controller compatibility should be confirmed against vessel-specific documentation.
✓ Intended for installation in protected, dry control panel environments such as engine control rooms or switchboard cabinets; mounting and wiring arrangements are subject to the original system design and installation drawings.
✓ Revision E designation indicates a specific engineering revision level; confirming the correct revision is important during replacement or retrofit to ensure functional and physical interchangeability within the existing system.
Marine Applications
✓ Offshore support vessels and platform supply vessels requiring reliable generator paralleling during dynamic positioning and variable load operations.
✓ Cargo vessels, bulk carriers, and tankers where multiple generating sets must be synchronized to the main switchboard as part of the vessel’s power management system.
✓ Passenger ferries and RoPax vessels where continuity of electrical supply is critical and generator changeovers must be executed smoothly and automatically.
✓ Naval auxiliaries and government vessels fitted with Woodward-based engine and power control systems requiring genuine or equivalent OEM synchronizer modules.
✓ Dredgers, crane vessels, and other electrically intensive workboats where switchboard automation and generator control reliability are operationally critical.
Why Marine Engineers Choose
Woodward synchronizer modules are trusted across the marine industry for their integration within established governor and power management architectures, offering a well-proven approach to automatic generator paralleling that supports operational reliability and reduces the risk of switchboard faults during generator transitions.
Ideal For
Suitable for fleet operators, ship managers, and vessel owners across offshore, merchant, passenger, and specialist marine sectors maintaining or upgrading Woodward-based power management and generator control systems.
Technical Support & Compliance
Technical assistance is available to support identification, compatibility checking, commissioning guidance, and integration into existing control systems — subject to confirmation of the installation details. To confirm suitability, buyers are encouraged to share nameplate photographs, the full part number and revision level, system model and software version, relevant wiring diagrams or installation drawings, and vessel name or IMO number where applicable. Retrofit and upgrade scope can be assessed upon review of the existing system configuration. All compatibility and interchangeability claims are subject to confirmation against vessel-specific documentation.
