Automatic Transfer Switch
Control Modules
DSE335 MKII
Auto Transfer Switch Control Module
The DSE335 MKII is an automatic transfer switch controller designed to monitor the voltage and frequency of incoming AC supplies from two different sources. These are either generator 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). Various timing sequences are available to prevent nuisance starting on minor supply breaks.
DSE334
Auto Transfer Switch Control Module
The DSE334 Automatic Transfer Switch Control Module monitors the voltage and frequency of an incoming AC supply from two different sources. These sources can be generator or mains (utility), or a combination of both.
DSE331
Auto Transfer Switch Control Module
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 generator or mains (utility), or a combination of both.
DSE327
Automatic Transfer Switch Controller
The DSE327 is an Automatic Transfer Switch Control Module designed to monitor the voltage of an incoming AC supply from two different sources. This could be from both generator 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.
