The thermal resistance values and the technical data referring to the cooling concept
of the "Cold Plate" variant indicated in the above table apply in the following condi-
tions:
no airflow
-
clearance of approx. 300 mm above and below as well as 100 mm on both the left
-
and right side of the frequency inverter
The energy dissipation values are valid for a switching frequency of 2 kHz. The
-
energy dissipation values are also valid for the other switching frequencies, as at
these operating points, the output current is reduced. For the output current re-
duction to be considered, refer to the chapter "Technical Data" in the instructions.
