APPLICATIONS

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.

The HJV Package provides additional mains protection.

Part-No. 8440-1668 SPM-D1040B/XN is a direct

replacement of the SPM-A synchronizer.
