Product Description

This unit is a Woodward synchronizer module, and classified as a part of their SPM-D21/PSXV category of Two Breaker Synchronizer and Load Control units. The designation of this unit is the 8440-1028 model in this series. It is outfitted with the standard SPM-D21/PSXV synchronization features and breaker components. This unit has a generator circuit breaker and a mains circuit breaker, and also includes a power factor control and load control. The 8440-1028 model is designed with synchronization capabilities for these circuit breakers, though can only synch them up one at a time. The phase matching and slip frequency synching occurs with the voltage matching. The 8440-1028 synchronizer has several operating capabilities, with a main parallel set of features and an isolated and dead bus operating capabilities. The mains parallel functions has a real power control, a power factor control, and a soft shutdown feature. The isolated features provide the frequency control and voltage control. The dead bus features provides closure for the circuit breaker modules within the 8440-1028. The 8440-1028 is equipped externally with a two-line text display unit, with LCD equipment. This unit is protected with multiple passwords as well, in order to keep the parameters set to the operator’s specifications. Physically, this unit is designed with a standard series of measurements, with a length of 144 mm, a height of 72 mm, and a depth of 122 mm. The frame includes a set of screw/plug terminals to connect the unit to the generator.
