APPLICATIONS

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.
