DIN devices heat radiation

Client is asked by ventilation company to calculate heat radiation which C-Bus dimmers/relays will give at full power. They have a big C-Bus board and need to calc AC system specs.

Searched docs and did not find any info on how hot can C-Bus device get during normal operation. Maybe it is set by some kind of standard which has C-Bus devices certified?

Anyone can help? Thank you.

 

Wouldn't it be easier to run the units and determine the heating load in the actual installation ?

 

Its not unusual to have these figures so heating calcs can be performed.

I see them all the time for all the PLC/DCS gear that I use and install and like a C-Bus unit, the loads will vary depending on what is connected.

It is a valid request by the cooling guys but it sounds like Clipsal may not [at worst case] have done the testing.

How can you do valid testing and publish the data ?

 

well, you just connect full load to the device and check it's body temperature?
I would do it if I could, but do not have a lab for it
