Product Overview
The Woodward 9905-001K is an SPM-A (Speed and Phase Matching) synchronizer used to automatically align generator voltage, frequency, and phase with a live bus before breaker closure. It continuously compares both sources and adjusts the governor until synchronization is achieved, enabling safe and precise grid connection.

FAQs
Does it support dead-bus closing?
No. It is designed for synchronizing an offline generator to a live bus; dead-bus control is handled elsewhere in the system.
What does the “K” suffix mean?
It indicates a specific hardware revision or configuration variant. Verify compatibility with your governor and wiring setup.
Can the phase angle tolerance be adjusted?
Yes. The synchronization window can be fine-tuned via internal or front-panel adjustments.
Is this a genuine unit?
Yes. It is supplied as 100% brand new original Woodward equipment.
