Front-end power supply goes digital

6-kW available power from 1U chassis with world-class power density of 22 W/in.3

The UFE series digitally programmable ac/dc front-end power supplies provide a world-class power density of 22 W/in.3 The power supplies have a 5.5 x 10.7-in. footprint and a height of 1.6 in., enabling up to three supplies to be contained on a single 1U-high 19-in. rack-mount chassis. The highest-power model in the series — the UFE2000 — has a 2-kW output rating, enabling power shelves with 6 kW. The power supplies can be stacked up to 6U high, providing up to 36 kW of available power. The supplies suit high-availability central office, telecommunications, and server-type applications, such as data centers.

The UFE series currently comprises two models: a 24-Vdc output model with a power rating of 1,300 W, and a 48-Vdc output with a power rating of 2,000 W. Both supplies generate an output and an auxiliary 260 mA at 11-Vdc output. The 1,300-W model has an input range from 90 to 264 Vac and delivers up to 65 A from its main output, while the 2,000-W model has a 180 to 264-Vac input, and delivers up to 52 A from its main output.

The main output is digitally programmable, and users have a choice of standard I2 C or advanced PMBus communications. The output of 48-Vdc model can be adjusted from 42 to 57 Vdc, while the output of the 24-Vdc model can be adjusted over the range 21 to 28.5 Vdc. The output voltage for both versions can be adjusted on the fly, with a setpoint accuracy of ±0.5%. (From $665 ea/100 — available now.)
