WinSystems Introduced Low-Cost 25W and 50W Embedded Power Supplies

Published:2012/2/17 1:39:00 Author:Amy From:SeekIC

WinSystems has introduced two small, convection cooled, AC/DC power supplies for embedded systems. One is the PS-RS25-5, which is a 25W unit capable of supplying +5Vdc at 5A while the 50W, PS-RS50-5, supplies +5Vdc at up to 10A. The short circuit and overvoltage protection will recover and return to normal automatically after the fault is removed. Both power supplies support 88 to 264VAC input from 47~63 Hz so that they can operate on AC mains in the world. The units operate from -20° to +70°C requiring no fan.

The units are certified with EMI, and EMC standards. Both are UL60950-1 and TUV EN60950-1 approved. For EMI and conduction and radiation, each unit complies with EN55022 (CISPR22) Class B. Additionally both power supplies are compliant with EN61000-4-2, 3, 4, 5, 6, 8, 11: ENV50204, EN61000-6-2 (EN50082-2) heavy industry criteria A for EMS immunity. The smaller PS-RS25-5 measures only 79 x 51 x 28mm. The slightly larger PS-RS50-5 measures 99 x 97 x 36mm.

Four different ordering options are provided for each power supply. These options come with a USA standard AC plug. The variations are defined by the DC harness for WinSystems’ embedded SBCs that conform to the PC/104, EPIC, EBX standards or with no DC harness at all.
