Called CUS350MP, the PSUs have medical and industrial safety certifications.
Input can vary across 85 to 265Vac (with leakage current <300µA).
Four output voltages are available: 24, 30, 36 and 48V, plus a 5V 300mA isolated stand-by voltage – remote on/off is also fitted as standard.
Typical full load efficiency is 94% with a 230Vac input.
Operating ambient is -20 to +70°C, derating linearly above 50°C to 30% load.
Input to output isolation is 4kVac (2 x MoPP), input to ground 1,5kVac (1 x MoPP) and 1,5kVac (1 x MoPP) output to ground for suitability in B and BF rated medical equipment.
Safety certifications include IEC/UL/CSA/EN 62368-1, IEC/EN/ES 60601-1, EN 62477-1 (OVC III), with CE marking to the Low voltage, EMC and RoHS Directives.
The units also comply with EN 55011-B and EN 55032-B conducted and radiated emissions, meet the EN 61000-3-2 harmonics, IEC60601-1-2 Edition 4 and IEC 61000-4 immunity standards.
Including the baseplate, the open frame models measure 88 x 183 x 44mm and weigh 770g.
A cover, screw terminal connections, double-sided board coating and a single AC fuse are available as options.
Applications are foreseen where occasional high peak power demands are experienced, for example medical equipment with DC motors and industrial printers.
