3.11 Power+ Coldplate models
The Power+ Coldplate (PSD10***A0) models are the same as respective standard Power+ models, with the unique
diff erence that the fi nned heatsink and fan are replaced by a fl at aluminium plate.
The plate has threaded holes M5 for fi xing an additional device with cooling function (coldplate), typically using
liquid refrigerant. The coldplate is the user’s responsibility and is not supplied by Carel.

Important:
• Make sure that the cooling device is dimensioned and fi xed to the plate in a way to dissipate the heat while
keeping the temperature of the plate below 70°C in the various operating conditions and that the overheating
alarm does not intervene.
• Make sure that the cooling device does not cause the formation of condensate on the inner surface of the plate.
• Clean the contact surfaces of the Power+ plate and of the coldplate and ensure they couple perfectly.
• The use of thermal compound or similar product, between the contact surfaces of the Power+ and the coldplate
allows better heat coupling.
• It is recommended that cooling device follows prescription as indicated in par. 4.4.5 of the EN 61800-5-1 Standard.
