Temperature derating
The derating characteristics assume the MicroFlex e150 is mounted vertically on
3 mm thick (or less) metal plate. If the MicroFlex e150 is mounted on 10 mm metal
plate, the current characteristics shown below can be increased by up to 7% if there
is no forced air cooling, or 15% if forced air cooling is present. See also Mounting and
cooling on page 29.
