The DSE335 is an Automatic Transfer Switch Controller. The DSE331 will monitor the voltage and frequency of the incoming AC supply from two different sources, which could be from both generator or mains (utility), or a combination of both. The module will monitor S1 (source 1) and in the event of a failure will issue a start command to S2 (source 2). Once S2 is vailable and producing an output within limits, the module will control the transfer device and switch the load from S1 to s2. Once the S1 supply returns to within limits, the module will command a load return to S1 and shut down S2.
