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

9907-028
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.
