The MPU-300S series is a family of compact 300-W AC/DC power supplies that are approved to EN 60950. Four standard models operate from a universal input of 90 to 264 Vac, providing regulated single outputs of 12, 15, 24, or 48 Vdc. The output is available factory-set within a range of 12 to 52 Vdc. Standard features include filtering to EN 55022 Class B, active power factor correction to EN 61000-3-2 D, peak output power to 600 W, reinforced insulation, and an I/O isolation of 3,000 Vac. All models are approved to EN 60950 and are protected for overload, overvoltage, overtemperature, and short-circuit faults.
All models include an on/off control input and a 12-V fan output as well as power-good and fan-fail signals. Per MIL HDBK 217F, the MTBF of the MPU-300S series is greater than 100 khrs. The power supply family is packaged in a 5.0 x 3.2 x 1.5-in. U-chassis. With 25-cfm airflow, they provide up to 300 W of output power.
