XP Power announced the SDH400 series of single- and dual-output 400 Watt power supplies. These compact 1U profile chassis mount units, measuring 203,0 x 127,0 x 40,64 mm, can deliver their full 400 W output without the need for any cooling fans or forced airflow.
The single-output models 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 startup currents such as that of a motor, but removes the need for a higher rated, larger and more costly power supply. 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 V d.c. Three dual-output models are available that offer output combinations of +5/+12 V, +5/+24 V or +12/+24 V d.c.
A trim function allows 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 over-voltage protection features are included as standard.
The full convection rating is available from 90 - 264 V a.c. input and the series operates over a wide temperature range of 0°C to +70°C with no derating until +50°C, suiting most global industrial power requirements without the need for derating.
The series meets safety approvals standard UL/EN 60950-1 and also conforms with the 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.
