The DSE500 is an Automatic Transfer Switch Control Module. It is designed to monitor the incoming AC mains supply (3 phase) for under voltage. Should this fall out of limits the module will issue a start command to the generating set controller. Once the set is available the ATS module will control the transfer devices and switch the load from the mains to the generating set. Should the mains supply return to within limits the module will command a return to the mains supply and stop requesting the generator.
