CUI: open frame AC-DC power supplies for medical applicationsERT

CUI’s Power Group announced the introduction of five new open frame series, ranging from 180 W up to 550 W, to its line of internal AC-DC medical power supplies 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 feature high efficiency up to 94% and high power densities up to 30 W/in3.

All of the new VMS series provide output voltage options from 12 to 58 VDC, feature wide universal input voltage ranges from 80 to 264 VAC, and offer no-load power consumption as low as 0.5 W. The 180 W to 550 W models also carry an input to output isolation of 4200 VAC with leakage current ratings as low as 0.3 mA at 230 VAC. Operating temperatures range at full load from -40 up to +50°C with forced air cooling, derating to 50% load at +70°C.

The new models are housed in 50×101 mm and 76×127 mm packages with profiles measuring as low as 19 mm, providing a compact, high density solution for medical diagnostic equipment, medical monitoring devices, and dental applications.
