The DSE 327 is designed to monitor the voltage of an incoming AC supply from two different sources. This could be from both generators or mains (utility), or a combination of both. The module monitors S1 (Source 1) and in the event of a failure issues a start command to S2 (Source 2). The DSE327 can be ordered in 110 V and 230 V variants. 

The DSE331 Automatic Transfer Switch Control Module monitors the voltage and frequency of an incoming AC supply from two different sources. These sources can be generators mains (utility), or a combination of both.

The DSE334MKII Automatic Transfer Switch Control Module monitors the voltage and frequency of an incoming AC supply from two different sources. These sources can be generators mains (utility), or a combination of both.

The DSE335MKII is an automatic transfer switch controller designed to monitor the voltage and frequency of incoming AC supplies from two different sources. These are either generators mains (utility), or a combination of both. The module monitors S1 (source 1) and in the event of a failure issues a start command to S2 (source 2). Various timing sequences are available to prevent nuisance starting on minor supply breaks.
