Description
WOODWARD
SPM-A
SYNCHRONIZER MODULE
PART NO 9907-028
REV. D
The Woodward SPM-A Synchronizer Module (part number 9907-028, Rev D) is a dedicated automatic synchronizing unit designed for precise generator paralleling within marine power management and control systems. As a core component of the Marine Control System category, it monitors and compares the voltage, frequency, and phase angle of an incoming generator against the live busbar, issuing close commands only when synchronization conditions are met. Reliable synchronization is operationally critical aboard vessels — improper paralleling can cause damaging load surges, equipment faults, and blackouts. The SPM-A ensures smooth, automatic generator connection, supporting safe and efficient power distribution onboard.
Key Features
✓ Automatic synchronizing function: continuously monitors voltage, frequency, and phase angle to enable safe, controlled generator paralleling without manual intervention.
✓ Technical specifications including input voltage ranges, response times, and output relay ratings are subject to confirmation based on configuration and revision level — reference the nameplate and Woodward documentation for precise values.
✓ Designed for integration within Woodward power management architectures and compatible switchboard or generator control panel installations; system compatibility is subject to confirmation against the specific panel configuration and software version.
✓ Typically installed within a protected electrical enclosure in the main switchboard or engine control room; mounting and environmental requirements should be verified against the original system drawings before installation.
✓ As a revision-controlled module (Rev D), sourcing the correct revision is important for drop-in replacement — verify the revision level against the existing installation to ensure functional and dimensional compatibility.
Marine Applications
✓ Main switchboard generator paralleling systems aboard merchant vessels, tankers, and bulk carriers where automatic synchronization is required for safe power management.
✓ Offshore support vessels, platform supply vessels (PSVs), and anchor handling tugs requiring reliable generator synchronization under variable load conditions.
✓ Cruise ships and passenger ferries where uninterrupted power supply and smooth generator changeover are essential to hotel load and safety systems.
✓ Naval auxiliaries and government vessels operating Woodward-based power management and control systems requiring OEM-specification synchronizer modules.
✓ Retrofit and upgrade projects on existing vessels where the original Woodward SPM-A module requires replacement as part of a switchboard overhaul or control system modernization.
Why Marine Engineers Choose
Marine engineers specify the Woodward SPM-A Synchronizer Module for its established role in automatic generator paralleling, its integration within recognized Woodward power management platforms, and the operational assurance that comes with sourcing an OEM-specified module for a safety-critical control function.
Ideal For
Merchant vessels, offshore support vessels, tankers, bulk carriers, passenger ships, ferries, and any vessel type operating Woodward-based generator control and power management systems requiring a reliable automatic synchronizer module.
Technical Support & Compliance
Technical support is available for remote troubleshooting, onboard diagnostics, commissioning assistance, and integration guidance for the Woodward SPM-A within your vessel’s power management system — all subject to confirmation of the specific installation details. Repair and retrofit assessments can be arranged depending on system scope and configuration. To confirm compatibility and suitability for your application, buyers are encouraged to share nameplate photographs, the full part number and revision level, relevant system drawings or panel schematics, the generator control panel model and software version, and vessel name or IMO number where applicable. All compatibility and interchangeability assessments are subject to confirmation upon review of the provided documentation.
