V-Infinity Announces New 250W Power Supply

November 29, 2006 by Jeff Shepard

V-Infinity introduced a new family of 250W switching power supplies that achieve a power density of 10.4 W/in³. The units are designed for a range of information technology, datacom, wireless, and industrial applications. Exact dimensions of the VF-S250 series measure 3.2 x 5 x 1.5 inches in the u-frame version and 3.2 x 5 x 2 inches in the metal-enclosed w/dc fan version. All models feature power factor correction (EN61000-3-2 class A), with a maximum power output of 250W with 16 C.F.M. of forced air cooling. Additionally, the power supplies are able to provide 600W of peak power within a 500 µS duty duration.

Input voltage is auto-selectable, ranging from 90~132Vac or 180~264Vac. Voltage outputs range from 2.0-60.0 Vdc on 10 different single-output models. The units produce full output power from 0 to 50°C and de-rating linearly from 50 to 70°C, at which point the VF-S250 still produces 50% output at 70°C. Control and protection features include remote on/off, over voltage, over current, over temperature, and short circuit protections. Safety approvals include UL/cUL/TUV/CE/CB.

OEM pricing starts at $73 per unit.
