AC/DC supplies offer high power density

-November 05, 2017

Expanding its VOF family of open-frame AC/DC power supplies, CUI introduces the VOF180 and VOF225A series, outputting 180 W and 225 W of continuous power, respectively. The power supplies achieve efficiencies of up to 94% and power densities of up to 30 W/in.3 Units in each series are housed in low-profile packages that occupy an industry-standard 2×4-in. footprint for use in ITE, industrial, and consumer electronics applications.

No-load power consumption for both the VOF180 and VOF225A series is less than 0.5 W. Operating over a wide input voltage range of 80 V to 264 V, the power supplies provide single outputs of 12 V, 15 V, 24 V, 30 V, 48 V, and 58 V. They are capable of operating over a temperature range of -40° to +50°C at full load with forced-air cooling, derating to 50% load at +70°C.

Other features of the VOF180 and VOF225A power supplies include a 12 VDC, 500 mA fan output; power factor correction; and overvoltage, overcurrent, and short-circuit protection. The two series also boast an MTBF of 3.37 million hours, calculated per Telcordia SR-332 Issue 3.

Prices for the VOF180 and VOF225A AC/DC power supplies start at $99.90 in lots of 25 units.
