Compact convection cooled power supply delivers 400 W without fans
July 2014, Electrical Power & Protection


XP Power has announced the SDH400 series of single and dual output 400 W convection cooled power supplies. These compact 1U profile chassis mount supplies can deliver the full 400 W 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 W 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 3-60 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 user adjustment of output voltage in the range ±5% of 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°C with no de-rating until 50°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.
