    Hello,
    Could someone please explain to me what the KNX power supply has that is so expensive? I would be grateful for an example diagram. (Question out of curiosity not out of a desire to save money).

    Greetings

    Guaranteed temperature range (tested, which costs money), testing for safety compliance (which costs money), EMC testing (which costs money), certifications (certification also costs money), bus, logo markup?
