Coupled with high efficiencies up to 94% and no-load power draw as low as 0.5W, these open frame AC/DC power supplies are suited for IT equipment, industrial, and telecom applications where space and energy consumption are of major concern.
The three new VOF series offer output voltage options from 12-58Vdc and feature wide universal input voltage ranges up to 80-264 Vac. Certified to the UL and EN 60950-1 safety standards, the power supplies further meet EN 55032 B requirements for conducted and radiated emissions. All models also provide power factor correction, a 12Vdc/500 mA fan output, and protections for over voltage, over current, and short circuit.
Operating temperatures range at full load from -40 up to 50°C with forced air cooling, de-rating to 50% load at 70°C. The high density AC/DC power supplies also carry an MTBF of 3.37 million hours, calculated per Telcordia SR-332 Issue 3.
