Emerson Network Power extends range of ADN-C series slim three-phase DIN rail power supplies

HONG KONG: Emerson Network Power has extended its line of ultra compact ADN-C series three-phase DIN rail mounting power supplies with new 10 A and 5 A models.

The power supplies are ideal for a wide range of heavy duty industrial applications – especially those involving large inductive loads – such as machine control, semiconductor fabrication, conveyor and material handling systems, including Class 1, Division 2 hazardous locations. Designed for high reliability, these new models have a mean time between failure (MTBF) of more than 500,000 hours, and are backed by a comprehensive five year warranty.

Designed to operate direct from standard three-phase inputs, the new Emerson Network Power ADN-C series power supplies have a wide 320 to 540 Vac input range, capable of accommodating virtually all standard line voltages worldwide. They are also capable of operating from a dc input, in the range 450 to 760 Vdc. The power supplies are very high efficiency designs: typically 85 percent for the new 5 A model and 91 percent for the 10A model.

Both new ADN-C series power supply models produce a single 24 Vdc output, which is user adjustable up to 28 Vdc. The 5 A ADN5-24-3PM-C is rated at 120 W and the 10 A ADN10-24-3PM-C at 240 W. A PowerBoost facility overcomes the disadvantage of output fold-over under the high peak current demands of switching large inductive loads, such as heavy duty relays, solenoids or motors. This can result in the device failing to activate or start.

PowerBoost provides 1.5 times the supply’s nominal current for a minimum of 4 seconds, while maintaining a 20 V output to ensure successful operation.

The power supplies have a nominal full load operating temperature range of minus 25 to 60 degrees Celsius without derating, and are intended for fanless convection cooling. They are extensively protected against overvoltage, overload and continuous shortcircuit conditions. A ‘DC OK’ relay output is also provided, for remote diagnostics and condition monitoring.

Emerson Network Power ADN-C power supplies meet all applicable international EMC emission and immunity standards – including the Semi F47 sag immunity standard for semiconductor fabrication equipment. The designs also comply with the EN 60950 Low Voltage Directive and the Restriction of Hazardous Substances (RoHS). Comprehensive safety approvals include UL 508 and UL/IEC 60950-1.

The ADN-C series three-phase power supplies are available now.
