XP Power SDH400 series 400 W convection-cooled power supplies

XP Power has announced the SDH400 series of single- and dual-output 400 W highly efficient convection-cooled power supplies. The compact 1U profile chassis-mount supplies, measuring 203 x 127 x 40.64 mm, can deliver the full 400 W output without the need for any cooling fans or forced air flow.

The single-output models have a peak power capability that allows them to deliver 700 W for up to 0.5 s. This feature is suitable 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 power supply being specified.

The range comprises nine models providing all the nominal output voltages from 3 to 60 VDC. Three dual-output models are also available that offer output combinations of 5/12, 5/24 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.
