Advanced Paralleling Gen-Set Controllers


Bus-Tie Controller
User Configurable as: Bus-Tie Controller / Load Switch Controller

The G8680 controls a generator bus-tie breaker. It automatically manages the synchronising of the 2 buses using the AMSC (advanced multi-set communications) link and has a built-in check sync function. The controller has been designed to work with the DSEG8600 when configured as a single-set / multi-set or mains (utility) controller and with the dedicated G8660 mains (utility) controller.
