Figure 7: Thermal Derating (max output current vs. ambient air temperature)

for airflow rates of 100 LFM through 400 LFM with air flowing lenghtwise from

input to output (nominal input voltage).

air flowing at the rate of 200 LFM. Air is flowing across the converter from

input to output (nominal input voltage).
