DSE509
Auto Mains Failure Control Module
The configurable Automatic Mains Failure Module allows many of the industry's demanding specifications to be achieved. Variations of the unit offer additional functions like RS232 interface for remote monitoring by a volt free relay module, annunciator or building management system.

The DSE509 is used to start a generator on a mains (utility) failure and transfer the load when the engine's operating criteria has been met. On return of the mains supply, the engine is returned to standby mode.
