WOODWARD 8440-1301 REPLACED BY 8440-2171, Synchronizer Pkg. X 400 Vac, SPM-D2-1040B/X
The SPM-D2-10 series are microprocessor-based synchronizers designed for use on three phase AC generators equipped with Woodward or other compatible speed controls and automatic voltage regulators. The SPM-D2-10 synchronizers provide automatic frequency, phase and voltage matching using either analog or discrete output bias signals. These synchronizers are applied to a wide range of prime movers and generators, as their control signals may be set to fit several types of gensets -- from fast-reacting diesel engines to soft-reacting gas turbines.
