The VOF-275, VOF-350, and VOF-550 series are housed in compact, low-profile form factors measuring only 76 x 127 x 19 mm with high power densities of up to 24.4 W/in³. With high efficiencies up to 94% and no-load power consumption as low as 0.5 W, these open-frame AC-DC power supplies are ideal for IT, industrial, and telecommunications applications where space and power consumption are critical.

The three new VOF series offer output voltage options from 12 to 58 Vdc and feature wide universal input voltage ranges from 80 to 264 Vac. Certified to UL and EN 60950-1 safety standards, the power supplies also 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 overvoltage, overcurrent, and short-circuit protection.

Operating temperatures at full load range from -40 to +50°C with forced air cooling, dropping to +70°C at 50% load. The high-density AC-DC power supplies also boast an MTBF of 3.37 million hours, calculated by Telcordia SR-332 Issue 3.
