Figure 1: Efficiency at nominal output voltage vs. load current for minimum,
nominal, and maximum input voltage at 25°C.
Figure 2: Power dissipation at nominal output voltage vs. load current for
minimum, nominal, and maximum input voltage at 25°C.
Figure 3: Maximum output power-derating curve vs. ambient air temperature
for airflow rates of 100LFM through 400LFM with air flowing from pin 3 to pin
1 (nominal input voltage - Base Plated Unit).
Figure 4: Thermal plot of converter (Open Frame) at 29A load current (350W)
with 25°C air flowing at the rate of 400LFM. Air is flowing across the converter
from pin 3 to pin 1 (nominal input voltage).
