Table 33: Technical data, ColdPlate 400V devices
The following points must be complied with to ensure the R
th
:
· The maximum heat sink temperature (T
kk
) of 80°C and the maximum internal temperature of
the control cabinet (T
amb
) of 40°C must not be exceeded.
· The ColdPlate and the mounting plate must lie flat against each other (max.air gap 0.05mm).
· The contact area of the mounting plate must be at least as large as the area of the ColdPlate
· A suitable heat conducting paste must be applied between the ColdPlate and the mounting
plate.
The heat conducting paste is not included in the scope of delivery! First remove any
protective film.
· All screw connections must be tightened.
· When designing a cooling system the heat to be dissipated by the ColdPlate device, Pv-
module must be taken into account. For the design of the control cabinet the heat production
of the device of approx 5% of the nominal power must be taken into consideration.
