Power supply redundancy modules for industrial harsh environments introduced by Emerson

ROSEMONT, Ill. – Emerson Industrial Automation in Rosemont, Ill., is introducing the SolaHD SDN2X power supplyredundancy modules for systems in hazardous industrial locations and harsh environments like petrochemical and gas facilities, industrial manufacturing, machine tools, wastewater treatment centers and power generation plants.

Emerson SolaHD SDN2X redundancy modules continuously monitor two power supplies connected in parallel. In the event one power supply fails, the SDN2X automatically changes over to the second power supply. This can eliminate the potential for single power supply failure causing an unexpected shutdown.

Because the power supplies are decoupled via the module, the operating power supply doesn't feed into the failed power supply. SolaHD SDN2X redundancy modules incorporate a MOSFET design which generates less heat than diode-based redundancy modules. Less heat translates to longer life of the components housed in the same enclosure as the power supply.

International certifications include UL, CSA, CE, ATEX, IECEx, ExEAC, ABS, and DNV-GL for operating in harsh environments, hazardous locations, and marine applications. SolaHD SDN2X redundancy modules have diagnostics via three bi-color LEDs, while a relay output provides power output status information to a PLC or other control equipment.

Three sizes of SDN2X redundancy modules are available. Each module supports redundancy between two 12- or 24-volt DC power supplies. Each of the two connected power supplies can have a capacity to 10, 20, or 40 amps.
