DSE333

Auto Transfer Switch Control Module

Features

The DSE333 is an Automatic Transfer Switch controller for genset and other applications. The module will monitor the voltage and frequency of the incoming AC mains (utility) supply and in the event of a failure, will issue a start command to the generator control system.

Once the generator is available and producing an output within limits, the DSE333 will control the transfer device and switch the load from the mains (utility) to the generating set.

Once the mains (utility) supply returns to within limits, the module will command a return to the mains (utility) supply and shut down the generator after a suitable cooling run.  Various timing sequences are available to prevent nuisance starting on minor supply breaks. 

The DSE333 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 modules can be easily configured using the DSE Configuration Suite PC software.  Selected front panel editing is also available.  Configurable volt-free digital inputs and outputs make the DSE333 fully
flexible to suite a wide variety of applications. When there is no DC supply, a compatible self-seeking power supply is available (DSE160).
