Figure 7: Maximum output power-derating curves vs. ambient air tem-
perature for airflow rates of 0 LFM through 400 LFM with air flowing
from input to output (nominal input voltage).
Figure 8: Thermal plot of converter at 14 amp load current (70W) with
55°C air flowing at the rate of 200 LFM. Air is flowing across the con-
verter from input to output (nominal input voltage).
