Seven standard models operate from a universal input of 90 to 264 VAC, providing tightly regulated single outputs. Outputs are factory set to 3.3, 5, 12, 18, 24, 36, or 48 VDC (all are user adjustable). Standard features include power factor correction to EN61000-3-2 D, 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 Good and Remote On/Off are provided, as well as a driver output for an external fan. As an option, models are available with current share capability. The MTBF (per MIL HDBK 217F) of the MPA500R series is greater than 150 khours. All models are approved to UL, cUL, and TUV. The series is certified to CE and is RoHS compliant.
The MPA500R family is packaged in a compact 8 x 4.3 x 2.5 inch U-Chassis. With only 30 CFM airflow, they provide 500W of output power, with a peak power capability of 900W. Package options include a cover, or enclosure with end-mount fan. Each model is specified for operation over the wide operating temperature range of 0°C to +50°C (ambient).
The MPA500R series is an ideal solution for a wide variety of high power applications requiring high performance, compact size and low cost. Applications would include distributed power networks, industrial bulk power systems, telecommunications equipment, and industrial automation systems.
