FEATURES

The DSE331 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 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.

Configurable digital inputs and

outputs make the DSE331 fully

flexible to suit a wide variety of

applications.

The module can be easily

configured using the DSE

Configuration Suite PC Software.

Where there is no DC supply a

DSE160 self seeking power supply

is required.

The DSE331 also supports many

topologies, and includes a clear

back-lit LCD display, showing

system operational status and

warnings.
