SPM-D10 Series


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.

Part-No. 8440-1668 SPM-D1040B/XN is a direct replacement of the SPM-A synchronizer.
