CUI’s Power Group has introduced five new open frame series. These range from 180W up to 550W, to its line of internal AC/DC medical power supplies. The devices are certified to the medical 60601-1 edition 3.1 safety standards for 2 x MOPP applications and 4th edition EMC requirements; the VMS-180, VMS-225, VMS-275, VMS-350, and VMS-550 series offers high efficiency up to 94% and high-power densities up to 30W/in3. The new models are housed in 2" x 4" (50mm x 101 mm) and 3" x 5" (76mm x 127 mm) packages with profiles measuring as low as 0.75" (19 mm). These offer a compact, high-density solution for medical monitoring devices, medical diagnostic equipment, and dental applications. These medical power supplies also meet EN 55011 Class B limits for conducted and radiated emissions and achieve an MTBF of 3.37 million hours, calculated per Telcordia SR-332 Issue 3.
