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.
