Th
e temperature rise assessment according IEC 60890 is recognized as a proven method for
most standard panels. It refers to cabinets with natural convection only. Th
e “Result Cooling +
Heater” tab provides some additional information and functionality.
Depending on the environmental conditions and the permissible inside temperatures,
TRCS calculates:
Necessary heating power to prevent condensation in the enclosure
•
Necessary heating power to maintain the minimal enclosure inside temperature
•
Required cooling capacity and / or air fl ow if the calculated inside temperature
•
would exceed the limit
Material of the enclosure/k-value
Beside the IEC 60890 standard value, there is a choice of diff erent enclosure materials with
diff erent k-values:
Try the diff erent enclosure materials. You will see, the IEC 60890 standard value
is pretty conservative.
Select “variable” if you want to enter an individual k-value provided by your enclosure supplier.
