The new models are housed in 50x101mm (2×4″) and 76x127mm (3×5″) 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.
