The PKM4000C series DC/DC converters can be
offered with a baseplate. Baseplate helps to cool
hotspots more efficient during heavy load. The
baseplate have approximately 5°C improved
derating compared to datasheet showing non
baseplated PKM4000C. The baseplate is intended
to be mounted on a cold wall to transfer heat away
from the converter. By mounting PKM4000C in this
way thermal derating can be improved by more
than 10°C .
