Operating Temperature: -40 to +85°C. Power derating details; please refer to the Derating Chart. Storage Temperature: -55 to +125 °C. Cooling: At least 100LFM moving air is recommended for full load > 0°C in a confined area. Air flow vs. power derating details, please refer to the Derating Chart. Power Density: 36.6 Watts / Cubic inch. Industrial Grade. NOTE: (1) All measurements are at nominal input, full load, and +25°C unless otherwise spec. (2) Line Regulation measured from High to Low Lines at full load. (3) Load Regulation measured from Full-Load (F-L) to Half-Load(H-L)at nominal input. (4) Correct fuse size by calculating the max. DC current drain at low Line input & adding 20-25% for desired fuse size. (5) Due to requests in market and advances in technology, specifications subject to change without notice. -149- INPUT/OUTPUT & VOLTAGE/CURRENT RATINGS CHART SINGLE OUTPUT OUTPUT VO1 ★# INPUT Vdc MODEL NO.
