Product:

The SPM–D11 is a microprocessor-based synchronizer designed for use on one or three-phase AC generators equipped with Woodward or other compatible speed controls and automatic voltage regulators. The SPM–D11 synchronizer provides automatic frequency, phase and voltage matching using either analog- or discrete output bias signals. It combines synchronizing for one circuit breaker, load and power factor control or isochronous load sharing and generator protection.

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

• Load/var sharing
