The Woodward 9905-003 SPM-A Synchronizer provides precise automatic generator synchronization for industrial power systems. It matches generator voltage, frequency, and phase angle before breaker closure. Moreover, the SPM-A series reduces synchronization time while protecting equipment from damaging transients. Operators rely on this controller when safe, repeatable grid connection is essential. Therefore, it supports both utility interconnection and islanded power system applications.
The SPM-A integrates easily with Woodward governors and voltage regulators. In addition, it offers stable performance in harsh electrical environments typical of power plants.
