Woodward SPM-D10B-PSY5-FU-D Automatic Synchronizer Unit

Product Description

The SPM-D10B-PSY5-FU-D is a microprocessor-based automatic synchronizer from Woodward SPM-D10 series. It is designed for single-phase/2-wire generator synchronization, providing automatic frequency, phase and voltage matching between generator and busbar. It outputs raise/lower relay signals to governor and AVR, and sends closing command to circuit breaker when synchronization conditions are satisfied. It is widely used in generator paralleling cabinets for power plant and marine power systems.
