DSE335

Automatic Transfer Switch Controller

Features

The DSE335 is an Automatic Transfer Switch Controller. The DSE335 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 available 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.

Various timing sequences are available to prevent nuisance starting on minor supply breaks.
 

The DSE335 supports many topologies and features include mains (utility) rated volt-free relays,
a clear back-lit LCD 4-line text display, showing system status and warnings and red and green LEDs
indicating operational status.

The module includes USB, RS232 and RS485 ports as well as dedicated DSENet® terminals for
system expansion, this gives features such as remote PC monitoring and SMS text alerts (with external modem).

The module can be easily configured using the DSE Configuration Suite PC Software.

Selected front panel editing is also available.

Configurable inputs and outputs make the DSE335 fully flexible to suit a wide variety of applications.
When there is no DC supply, a compatible self-seeking power supply is available (DSE160).
