Description
This is one of the advanced models of Woodward’s set of regulators and control modules,
the SPM-A series, the unit 9907-028, designed to be a similar model to the less advanced 9905-001
unit in the family. The 9907-028 model is designed to check the phase Angle and frequency of the
common bus, then check the off-line generator it is to connect to, and then parallel. Voltage inputs from
the bus and generator are used to separate the signal conditioner circuits, which change the shape of the
voltage input signal for accurate measurement. The phase Angle of 9907-028 is given in the range of a plus
or minus 10%. The 9907-028 is one of the few Woodward SPM-A synchronizers that does not have any
voltage matching feature.
