These AC/DC switchers include an autoranging 90V AC to 264V AC input, power factor correction, full safety approvals, and filtering. Ten standard models operate from a autoranging inputs of 90V AC to 132V AC, or 180V AC to 264V AC. Outputs are factory set to DC increments of 5V, 9V, 12V, 15V, 18V, 24V, 28V, 36V, 48V or 54V (all are user adjustable). Standard features include power factor correction to EN61000-3-2 A, FCC class B emissions, input/output isolation of 3,000V AC, 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 MPA250x series is greater than 100 khours. All models are approved for UL, cUL, TUV, CE, and RoHS.
