This device belongs to Woodward Inc.’s series of synchronizer modules, intended for three-phase, alternating current, industrial generators. This unit is listed under the numerical designation of 8440-1667. The 8440-1667 is classified as a unit in the SPM-D10/XN series of Woodward synchronizers. They are most compatible with industrial generators outfitted with an automatic voltage regulator unit, as well as a speed control module. It is not required for these components to be Woodward designed materials, only that they are built with a similar design. The 8440-1667 is outfitted with a series of functionalities, providing generator operators with automatic frequency matching, phase matching, and voltage matching. This unit is able to do this by either the discrete or analog speed and voltage outputs, which are both integrated into this unit. The other models of the SPM-D10 synchronizers have either discrete or analog. The 8440-1667 model is outfitted with a two-line, LCD display which provides information on the unit’s front facing side. This display also indicates when any alarms are active within the generator system, and allows for clarity when inputting operations or adjusting parameters. This unit’s dimensions are 144 mm/72 mm/122 mm, while the weight is approximately 800 grams.
