The SPM-D10 is a microprocessor-based synchronizer designed for use on three phase AC generators equipped with Woodward or other compatible speed controls and automatic voltage regulators. The SPM-D10 synchronizer provides automatic frequency, phase and voltage matching using either analog- or discrete output bias signals.

Synchronizing:

· Phase match or slip frequency synchronization with voltage matching

· Two-phase sensing of generator and bus

· Selectable operating modes like SPM-A (Run, Check, Permissive, and OFF)

· Synchro-check possible

· Synchronization time monitoring

Isolated operation:

· Frequency control

· Voltage control
