CUI, high Density AC-DC power supplies housed in open frame packages

Posted 30 October 2017

CUI’s Power Group 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 76x127x19 mm with high power densities up to 24.4 W/in³. Efficiencies is up to 94% and no-load power draw as low as 0.5 W.

The three new VOF series offer output voltage options from 12 to 58 VDC. All models also provide power factor correction, a 12 VDC/500 mA fan output and protections for over voltage, over current and short circuit.

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.

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 power supplies also carry an MTBF of 3.37 million hours, calculated per Telcordia SR-332 Issue 3.
