SPM-A Synchronizer WOODWARD 9905-002 for Engine-Generator Systems

Description

TheWoodward 9905-002 SPM-A Synchronizeris part of theSPM-A series, designed forautomatic synchronization of generator sets and utility buses. It continuously monitorsvoltage, frequency, and phase angleof the incoming and reference sources, adjusting the offline generator’sspeed and voltageuntil synchronization conditions are met. Once aligned, the module issues abreaker close command, enabling seamless connection. The 9905-002 supportsmanual and automatic modes, giving operators flexibility during commissioning and maintenance. Itscompact, rugged designis suitable forpanel mounting in harsh industrial environments. The module is widely used inpower generation, marine, and industrial automation systemswhere reliable synchronization is critical. Compatibility withWoodward speed controls and voltage regulatorsensures smooth integration into existing control architectures. The synchronizer also includesLED indicatorsfor status and fault diagnostics, simplifying troubleshooting and system monitoring.
