Open frame power supplies approved for medical applications

Five new open frame series, ranging from 180-550W, have been added to CUI Power Group's 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 30W/in3.

The new models are housed in 50x101mm (2x4") and 76x127mm (3x5") packages with profiles measuring as low as 19mm (0.75"), providing a compact, high density solution for medical diagnostic equipment, medical monitoring devices, and dental applications.

All of the new VMS series provide output voltage options from 12-58VDC, feature wide universal input voltage ranges from 80-264VAC, and offer no-load power consumption as low as 0.5W. The 180-550W models also carry an input to output isolation of 4,200VAC with leakage current ratings as low as 0.3mA at 230VAC.

Operating temperatures range at full load from -40 up 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 12VDC/500mA fan output.

These medical power supplies further 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.
