Product Description
DSE335 MKII Automatic transfer switch controller
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.

SPECIFICATIONDC SUPPLYCONTINUOUS VOLTAGE RATING
8 V to 35 V Continuous
CRANKING DROPOUTS
Able to survive 0 V for 50 mS, providing supply was at least 10 V before dropout and supply recovers to 5 V. This is achieved without the need for internal batteries.
LEDs and backlight will not be maintained during cranking.
