Woodward 9905-001 Module | 115/230VAC Turbine Sync Control

Woodward 9905-001 SPM-A Speed Synchronizer and Regulator

The 9905-001 (Model: 9905-001) is a specialized SPM-A (Synchronizer Power Module - Analog) designed for precision speed synchronization and frequency matching in power generation systems. This module is engineered to bridge the gap between a generator and the utility bus, ensuring that the incoming machine's phase, frequency, and voltage are perfectly aligned before the circuit breaker closes. The 9905-001 (Part Number: 9905-001) is essential for preventing the catastrophic mechanical stress and electrical surges associated with out-of-phase synchronization.

Operating on a dual-voltage platform (115/230 VAC), the 9905-001 (Synchronizer: 9905-001) provides a high-fidelity bias signal to the engine governor. Its design incorporates a 10 Amp relay capacity, allowing it to interface directly with heavy-duty breaker trip and close coils. While legacy documentation sometimes associates this family with the ProTech-GII series, the 9905-001 (Part Number: 9905-001) is fundamentally an analog speed regulator and synchronizer, prized for its deterministic response and reliability in diesel, gas engine, and steam turbine applications where a 50/60 Hz stable grid connection is mandatory.
