The MPU-360 series ac/dc switching power supplies provides 360W of output power in a 1U height U-Chassis case with 18 CFM of airflow. Four standard models operate from a universal input of 90 to 264 Vac, providing tightly regulated single outputs of 12, 24, 36, or 48 Vdc. Standard features include active power factor correction to beyond 0.99, filtering to EN55022 Class B, input/output isolation of 3 kVac, and a low safety ground leakage current. All models are protected for over-load, over-voltage, over-temperature, and short-circuit faults. MTBF per MIL HDBK 217F is greater than 120,000 hours. MICROPOWER DIRECT, Stoughton, MA.
