AUTO TRANSFER SWITCH CONTROL MODULE
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).

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

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.

ELECTRICAL SAFETY
BS EN 60950
Safety of Information Technology Equipment,
including Electrical Business Equipment

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.

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.
