2.2 SK 5xxE…-CP in ColdPlate version
Instead of a cooling element/fan, ColdPlate versions of the frequency inverter have a flat metal plate
on the rear side which is mounted on an existing mounting plate (e.g. the rear wall of the control
cabinet) so as to provide thermal conduction. A liquid cooling medium (water, oil) may also be passed
through the mounting surface. In this way, not only is the waste heat from the frequency inverter
dissipated more effectively, but also the waste heat from the inverter is prevented from remaining
inside the control cabinet. In addition to the optimisation of the power reserved and the service life of
the inverter, this also causes less thermal load on the inside of the control cabinet.
A further advantage of the ColdPlate version is the reduced installation depth of the device and the
fact that in general, there is no need for a fan on the frequency inverter.
Bottom-mounted brake resistors (SK BR4-…) cannot be mounted directly.
