Smallest 1U Height, 320W Power Factor Corrected AC/DC Power Supplies


Available immediately from MicroPower Direct, the MPA320x series provides 320W of output power in a very small 1U height U-Chassis. These AC/DC switchers include an autoranging 90 to 264 VAC input, power factor correction, full safety approvals and robust filtering. These high performance , industrial power supplies are ideal for a variety of applications requiring compact construction, high power density, and low cost.

Ten standard models operate from a autoranging inputs of 90 to 132 VAC or 180 to 264 VAC, providing tightly regulated single outputs. Outputs are factory set to 5, 9, 12, 15, 18, 24, 28, 36, 48 or 56 VDC (all are user adjustable). Standard features include power factor correction to EN61000-3-2 A, FCC class B emissions, input/output isolation of 3,000 VAC, and 20 mS hold-up time. All models are protected for over load, over voltage, over temperature 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. The MTBF (per MIL HDBK 217F) of the MPA320x series is greater than 100 khours. All models are approved to UL, cUL, and TUV. The series is certified to CE and is RoHS compliant.

The MPA320x family is packaged in a compact 6 x 4 x 1.5 inch U-Chassis. With only 22 CFM airflow, they provide 320W of output power. Package options include a cover (finger safe), Enclosure with end-mount fan or enclosure with top-mount fan. Each model is specified for operation over the wide operating temperature range of 0°C to +70°C (ambient).

The MPA320x series is an ideal solution for a wide variety of high power applications requiring high performance, compact size and low cost. Applications would include low profile systems in industries such as machine/process control, telecommunications, data processing and industrial automation.
