Figure 2-3
Aluminum air heat sinks are recommended.
The heat sinks and fans must be dimensioned for the power loss to be dissipated. For the
component-specific power loss in rated operation, refer to "Technical data". (Mean power
loss in periodic duty is lower.)
The heat sinks and fans are not part of the scope of supply.
Recommended suppliers for heat sinks include:
Alcan, Singen: http://www.alcan.com
Sykatec, Erlangen: http://www.sykatec.de
Note
The mounting surface for the heat sink (roughness, evenness) must fulfill the requirements
described in "Installing External Heat Sinks".
