Compact 800-W AC-DC Supplies Eye Industrial Power Apps

MicroPower Direct’s MPU-800S ac-dc power supplies deliver 800 W of output power in U-channel packaging. Features include filtering to EN 55022 Class B, active power-factor correction to EN 61000-3-2 D, peak output power to 900 W, and I/O isolation of 3000 V ac. Models operate from a universal input of 90 to 264 V ac, which provides tightly regulated single outputs. Outputs are set to 12, 24, or 48 V dc, but are customizable (through the company) over a range of 2 to 60 V dc. Overload, overvoltage, overtemperature, and short-circuit protection is included. N+1 curent share can be used to connect up to four units. Mean time between failure (per MIL HDBK 217F) is greater than 150 khours. Operating temperature ranges from 0 to 70°C (ambient). Targeted applications include industrial power that demands high power density and robust performance at low cost.
