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.
The module is configured using the DSE Configuration Suite PC Software. Selected front panel editing is also available. Configurable inputs and outputs make the DSE335 MKII fully flexible to suit a wide variety of applications.
