    Hello, I am looking for a well made transformer rectifier with current regulation and to have real ones at least 9A. I want it to reach 16.2V.

    I found HERTZ 12V 15A link

    but it looks a bit like the poor and well-known Stefpol EST-305 in the forum. Has anyone undressed or undressed him?

    Stefpol, Romstan now Hertz and God knows under what name they still produce it.
    I'm afraid it's still duplicating the same dug construction.
    I would advise against, although I did not see Hertz from the inside, but I saw Stefan and Romstan
    and that's enough for me (to this day I don't sleep at night :D )

    Everything is usually patted on one hoof - the difference is in the transformer itself and the way of controlling the power. Either there is a toroid controlled by a phase regulator, with a curiosity in the form of a compact coil of resistance wire for loading the transformer, or an EI transformer with taps. The rest in the same "technology".

    Well, gentlemen, what do you recommend? I was browsing the Internet, shops and auctions but it seems to me that everything is one hoof. Maybe you have something better? Let's say I could spend PLN 400 on it

    link Although there is no smooth regulation but maybe better made?

    In today's flood of trash it is difficult to catch something sensible - durable and functional.

    Ultimately submit something yourself.
