Front Ends Boast High Power Density
Delivering up to 2,000 W in a 5.5" × 10.7" × 1.6" package, the UFE series of programmable AC/DC front-end power supplies from Emerson Network Power yield a power density as high as 22 W/in³. Up to three supplies can deploy on a single 1U high 19"rack for up to 6 kW of available power, and up to 4 kW of redundant power. The power supplies can also be stacked up to 6U high, to provide up to 36 kW of available power. The series currently comprises two models, a 24-Vdc output model with a power rating of 1,300W, and a 48-Vdc output model with a power rating of 2,000W. Both power supplies generate a main payload output and an auxiliary 260 mA at 11 Vdc for powering standby circuitry. The 1,300W model has a range of 90 to 264 Vac input and can deliver up to 65 A from its main output. The main output of each power supply is isolated and floating, enabling positive or negative polarity operation, and has a hold-up time of 20 ms minimum at full rated power.
