ARLINGTON, Texas, 27 Feb. 2012. WinSystems debuts its 25-watt PS-RS25-5 and 50-watt PS-RS50-5 small, convection-cooled, AC/DC power supplies for embedded systems. The PS-RS25-5 measures 79 x 51 x 28mm, whereas the PS-RS50-5 measures 99 x 97 x 36mm.

The devices’ outputs have short circuit and overvoltage protection, which will recover and return to normal automatically after the fault is removed. Both power supplies accept 88 to 264 volts AC input from 47~63 hertz so they can work on AC mains throughout the world. The units operate from -20° to +70°C without the need for a fan.

Each unit meets safety, 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. Both power supplies are compliant with EN61000-4-2, 3, 4, 5, 6, 8, 11: ENV50204, and EN61000-6-2 (EN50082-2) heavy industry criteria A for EMS immunity.

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