【英文介绍】

Unit 8440-1028 is a synchronizer module that is classified as part of two circuit breaker synchronizers and load control units in the SPM-D21/PSVX category. The designation of the device is Model 8440-1028 in the series. It is equipped with standard SPM-D21/PSVX synchronization function and circuit breaker assembly. The unit has a generator circuit breaker and a power circuit breaker, and also includes power factor control and load control.

Models 8440-1028 are designed to synchronize these circuit breakers, although only one can be synchronized at a time. Phase matching and slip frequency synchronization are performed at the same time as voltage matching. The power parallel function has the functions of actual power control, power factor control and soft shutdown.

Isolation features provide frequency control and voltage control. The dead bus function provides closure for the circuit breaker module in 8440-1028. The 8440-1028 is externally equipped with a two-line text display unit, and with the LCD device, the LDC display on the controller will have a two-line display for alarms and operation instructions that occur on the controller.

When you use the controller, be aware that it has over/under voltage generator protection, and the ANSI number for this feature will be 59 or 27. The model's control output includes a speed bias that can be configured to 500 Hz and also has adjustable voltage levels.
