    Hello
    I have a 60W / 12V LED power supply, which was connected the other way around, i.e. a Led strip was connected to the 230v input and the voltage from the mains was supplied to the 12v input. What could be damaged first? The fuse in the switchboard worked very quickly. I am waiting for your answers. If photos of the power supply are needed, I can do it and upload it.

    The entire power supply burned as quickly as the power supply ;)
    The repair is completely unprofitable, you would have to put a new power supply inside.

    The quickest way to do this is to damage the power supply, if you would at least give it what model it is (model name, etc ...), you could be "guessing", but without measurements, no one will show you the damaged components.
    Ps. You cannot put the meter on the photo :cry: . (it means it is possible but the meter will show ----)

    After such a connection (switching the power supply with the output), you can expect quite a havoc (although everything is all right, you won't see it).

    20-30 PLN costs a new one. What is there to wonder about?
