Automatic Transfer Switch Control Modules

DSE705

Auto Transfer Switch Control Module

The DSE705 is an Automatic Transfer Switch Control Module for use with generator applications. The module monitors an incoming mains (utility) supply and issues a start command to the generator control system when the power fails.   

When the generator is producing the required output the DSE705 switches the load from the mains (utility) supply. When the mains (utility) supply returns the DSE705 switches the load back. The generator is instructed to cool down and stop.
