The DSE4130 is an Automatic Transfer Switch controller for genset and other applications. The module will monitor the voltage and frequency of the incoming AC mains (utility) supply and in the event of a failure, will issue a start command to the generator control system. When the mains (utility) returns the module transfers the load back and removes the start command. The generator should then begin its shutdown procedure. The Generator Control module can be configured so that it follows the users pre-set start and stop sequences. The DSE4130 enclosure has a closed back.
