About the 8440-1028
The 8440-1028 unit is a synchronizer module and is classified as a part of their SPM-D21/PSVX 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/PSVX synchronization features and breaker components. This unit has a generator circuit breaker and a mains circuit breaker and also includes power factor control and load control.
The 8440-1028 model is designed with synchronization capabilities for these circuit breakers, though can only sync them up one at a time. The phase matching and slip frequency syncing occur with the voltage matching. The mains parallel functions have a real power control, a power factor control, and a soft shutdown feature.
The isolated features provide frequency control and voltage control. The dead bus feature 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, the LDC display on your controller will have a two-line display which is used for alarm and operation indication that is occurring on your controller.
While you are using your controller note that it has generator protection for over/under voltage, the ANSI number for this function will be fifty-nine or twenty-seven. The control output for this model includes a speed bias which can be configured to a Hz out of 500 and also has an adjustable voltage level.
