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 20 amp load current (240W)

with 55°C air flowing at the rate of 200 LFM. Air is flowing across the

converter from input to output (nominal input voltage).
