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. 5. Transient response is specified with 270µF electrolytic and 10µF ceramic at the converter output pins. 4118 14th Avenue, Suite 4 Markham, Ontario L3R 0J3 1-905-944-2850 www.cd4power.com QUS20-120_084-20868-40_RevB_Jan18-2006.fm 4607 S.E.
