Ambient Air Temperature (°C)
Figure 7: Maximum output power-derating curves vs. ambient air tem-
perature for airflow rates of 100 LFM through 400 LFM with air flow-
ing from input to output (nominal input voltage).
Figure 8: Thermal plot of converter at 6.25 amp load current (75W)
with 55°C air flowing at the rate of 200 LFM. Air is flowing across the
converter from input to output (nominal input voltage).
