Original Press Release

Compact 1U Convection Cooled Power Supply Achieves 400 Watts without Fans

Press release date: May 1, 2014

XP Power today announced the SDH400 series of single and dual output 400 Watt highly efficient convection cooled power supplies. These compact 1U profile chassis mount supplies, measuring 8.0 x 5.0 x 1.6 inches (203.0 x 127.0 x 40.64 mm) can deliver the full 400 Watt output without the need for any cooling fans or forced air flow. The single output models also have a peak power capability that allows them to deliver 700 Watts for up to 0.5 seconds. This feature is ideal for accommodating applications that have momentary high start-up currents such as that of a motor, but removes the need for a higher rated, larger and more costly power supply being specified. Efficiency is typically 88% for single output models and 85% for duals.

The SDH400 single output range comprises nine models providing all the popular nominal output voltages from +3 to +60 VDC. Three dual output models are also available that offer output combinations of +5/+12 VDC, +5/+24 VDC or +12/+24 VDC. A trim function allows the user adjustment of output voltage in the range +/-5% of stated nominal to make up for load losses or to cater for non-standard voltage requirements. Power OK signal, remote on/off control, short circuit and overvoltage protection features are included as standard.

The full convection rating is available from 90-264 VAC input and the series operates over a wide temperature range of 0 to + 70 degrees C with no derating until +50 degrees C, meaning the SDH400 series will suit most global industrial power requirements without the need for de-rating.

The series meets safety approvals standard UL/EN 60950-1 and also conforms with EN55022 class B standard for conducted and radiated emissions.

Optional Molex input and output connectors are available in place of the standard screw terminal blocks.

The SDH400 series is priced at $319.18 for 500 pcs orders and is available from Newark, Digi-Key, or direct from XP Power and come with a 3 year warranty.
