Active Pfc 320-w Supplies Fit In 1u Space

摘要

The MPA321x series ac/dc power supplies provide 320-W output power in a 1U-height in a 6 × 4 × 1.5-in. U-chassis. Ten standard models operate from a universal input of 90 to 264 Vac, outputs are factory set to 5, 9, 12, 15, 18, 24, 28, 36, 48 or 56 Vdc, but are available from 2 to 60 Vdc. Standard features include active power factor correction to EN61000-3-2 D, filtering to EN55022 Class B, input/output isolation of 3,000 Vac, and a peak output power of 700 W. All models are protected for overload, overvoltage, overtemperature, and short-circuit faults. Interface signals for power-on, power-good, and fan-fail are provided, as well as a driver output for an external fan. Each model provides an operating range from 0° to 50℃ (ambient).
