ATS 335MKII

Auto Transfer Switch Control Module

The DSE335MKII is an automatic transfer switch controller designed to monitor the voltage and frequency of incoming AC supplies from two different sources. These are either generators mains (utility), or a combination of both. The module monitors S1 (source 1) and in the event of a failure issues a start command to S2 (source 2). Various timing sequences are available to prevent nuisance starting on minor supply breaks.

  • The DSE335 MKII is an automatic transfer switch controller designed to monitor the voltage and frequency of incoming AC supplies from two different sources. These are either generator mains (utility) or a combination of both. The module monitors S1 (Source 1) and in the event of a failure issues a start command to S2 (Source 2).
  • Once S2 is available and producing an output within limits, the module controls the transfer device and switches the load from S1 to S2. Once the S1 supply returns to within limits, the module commands a load return to S1 and shuts down S2.
  • Various timing sequences are available to prevent nuisance starting on minor supply breaks.
  • The DSE335 MKII supports multiple topologies. Features include a configurable close transition menu down to <100 ms, combined switching schemes, 415 V AC sensing for 600 V 3-phase system support, mains (utility) rated volt-free relays, a clear back-lit LCD 4-line text display, showing system status and warnings and bi-colour LEDs indicating operational status.
  • The module includes USB and RS485 ports and dedicated DSENet® terminals for system expansion.
  • The module is configured using the DSE Configuration Suite PC Software. Selected front-panel editing is also available.
  • Configurable inputs and outputs make the DSE335 MKII fully flexible to suit a wide variety of applications.
  • When no DC supply is available, a compatible DSE self-seeking power supply (DSE160) is available to order
