Description
WOODWARD 8440-1546H Synchronizer Governor/Control Unit
The
WOODWARD 8440-1546H is a high-performance synchronizer governor designed for generator set control in power generation and distributed energy systems. As part of Woodward’s SPC-D2 series, it ensures precise synchronization, load sharing, and protection for diesel, gas, or steam turbines. Key features include slip-frequency synchronization with phase/voltage matching, soft unloading, and dual-language support (English/German). With password protection and configurable settings via HMI or Woodward’s USB toolkit, the 8440-1546H offers flexibility for complex applications while reducing downtime through online configuration.

- Marine propulsion
Case Study:
A utility-scale microgrid in California improved synchronization accuracy by 30% using the 8440-1546H, reducing generator tripping during grid transitions.
Compared to generic synchronizers, the 8440-1546H offers:
- Integrated Functionality: Combines synchronization, load control, and protection in a single unit.
- Longevity: 20+ years of field-proven reliability in Woodward’s SPC-D lineage.
- Ease of Use: Pre-configured templates and USB programming simplify setup.
- System Compatibility: Verify CANbus compatibility with engine ECUs (e.g., Caterpillar, Cummins).
- Voltage Range: Match input voltage requirements for grid or off-grid applications.
- Expansion Needs: Opt for models with additional I/O if future upgrades are planned.
-
Mounting: Install in a well-ventilated area away from electromagnetic interference.
-
Firmware Updates: Regularly update via Woodward’s Toolkit software to access new features.
-
Spare Parts: Stock critical components (e.g., relay modules) to minimize downtime.
