Figure 2: Efficiency at nominal output voltage and 60% rated power vs. airflow rate for ambient air temperatures of 25 °C, 40 °C, and 55 °C (nominal input voltage). Figure 3: Power dissipation at nominal output voltage vs. load current for minimum, nominal, and maximum input voltage at 25 °C. Figure 4: Power dissipation at nominal output voltage and 60% rated power vs. airflow rate for ambient air temperatures of 25 °C, 40 °C, and 55 °C (nominal input voltage). Figure 5: Maximum output power-derating curve vs. ambient air temperature for airflow rates of 100 LFM through 400 LFM with air flowing from pin 1 to pin 3 (nominal input voltage). Figure 6: Thermal plot of converter at 41.4 A load current (420 W) with 55 °C air flowing at the rate of 200 LFM. Air is flowing across the converter from pin 1 to pin 3 (nominal input voltage).
