Five open-frame series from CUI Inc., ranging from 180 W up to 550 W, 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 feature energy efficiency up to 94% and power densities up to 30 W/in³. The new models sit in 2 x 4-in. (50 x 101 mm) and 3 x 5-in. (76 x 127 mm) packages with profiles measuring as low as 0.75 in. (19 mm), providing a compact, high-density supply for medical diagnostic equipment, medical monitoring devices, and dental applications.

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 4,200 Vac with leakage current ratings as low as 0.3 mA at 230 Vac. Operating temperatures range at full load from -40 to +50°C with forced air cooling, derating to 50% load at +70°C. Additional features include protections for over voltage, over current, and short circuit, power factor correction, and a 12 Vdc/500-mA fan output.

These medical power supplies further meet EN 55011 Class B limits for conducted and radiated emissions and reach an MTBF of 3.37 million hours, calculated per Telcordia SR-332 Issue 3.

The VMS series are available immediately with prices starting at $108.94 per unit at 25 pieces through distribution. Please contact CUI for OEM pricing. ( )
