Vin = 48Vdc, Ta = 20°C, Airflow = 200LFM unless otherwise noted. 2. Input Reflected Ripple Current is specified when measured with a 120µF 63V electrolytic capacitor across the input pins. 3. Output Ripple Voltage is specified when measured with a 270µF electrolytic and a 10µF ceramic capacitor at the converter output pins. 4. De-rating curves are conducted in a controlled environment. End application testing is required to ensure the hot spot temperature is below the maximum specified. Recommended airflow direction is input to output or cross-wise. For output to input airflow subtract 3A from derating curves. 5. Transient response is specified with 270µF electrolytic and 10µF ceramic at the converter output pins. 1150 Eglinton Avenue East Toronto, Ontario M3C 1H7 1-866-740-1232 www.cd4power.com QUS20-120-NHDR_084-20859-00_RevK_Jan30-2006.fm 4607 S.E.
