Convection-cooled power supply delivers 400 W
Single output models also have a peak power capability that allows them to deliver 700W for up to 0.5 sec, for 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. The SDH400 series is available from Farnell, element14, Digi-Key, regional distributors, or direct from XP Power and come with a 3 year warranty.
