The Des 530 is a fully configurable Automatic Transfer Switch control module. Should these fall out of limits, the module will issue a start command to the generating set controller. It is designed to monitor the
incoming AC mains supply (1 or 3 phases) for under/over voltage and under/over frequency. Once the set is available and producing an output within limits, the ATS module will control the transfer devices
and switch the load from the mains to the generating set. Should the mains supply return to within limits the module will command a return to the mains supply and shut down the generator after a suitable cooling run. Various timing sequences are used to prevent nuisance starting and supply breaks.

Specifications:

DC SUPPLY

The 530 is normally powered from the AC sensing supplies. It will only draw power from the DC supply if both AC supplies are not present. The module DC is powered from the plant battery or from a low voltage supply between 8 V to 35 V Continuous. It is able to operate at 0 V for 50ms during cranking, providing supply was at least 10 V before dropout and supply recovers to 5 V. This is achieved without the need for internal batteries.

MAXIMUM OPERATING CURRENT

150mA @ 12V, 95mA @ 24V.
