19. Operating Temperature Range
The CPFE1000FIxx can be mounted in any direction; however, careful consideration should be given to
avoid heat accumulation around the module. Verify baseplate temperature at worst case operating condition
at the measurement point as shown on page 34. The baseplate temperature must be maintained at or below
85°C on all models.
Due to the temperature limit of other components in the power supply that are not directly installed on the
base plate, the ambient temperature must also be maintained at or below the maximum limits. Figure 19- 1
shows the orientation of the power supply that corresponds to the orientation listed in the derating tables. The
tables below show the de-rated output power at different ambient temperatures and orientations.
