Original Press Release:

High Density AC-DC Power Supplies Housed in Low Profile, Open Frame Packages

CUI’s Power Group today announced the addition of 275 W, 350 W, and 550 W models to its VOF family of open frame ac-dc power supplies. The VOF 275, VOF 350, and VOF 550 series are housed in compact, low profile packages measuring as small as 3 x 5 x 0.75 in (76 x 127 x 19 mm) with high power densities up to 24.4 W/in3. Coupled with high efficiencies up to 94% and no-load power draw as low as 0.5 W, these open frame ac-dc power supplies are ideally 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 to 58 Vdc and feature wide universal input voltage ranges up to 80 to 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 12 Vdc/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, derating 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.

The VOF 275, VOF 350, and VOF 550 series are available immediately with prices starting at $119.48 per unit at 25 pieces through distribution. Please contact CUI for OEM pricing.
