    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.

Topic summary

The discussion centers around the comparison of two transformer rectifiers: the Hertz 12V 15A and the Stefpol EST-305. Users express concerns about the quality and construction of these devices, suggesting that many brands, including Stefpol and Romstan, may share similar designs and manufacturing processes. There is a consensus that the performance of these rectifiers is often subpar, with a focus on the importance of transformer type and power control methods. One user highlights the weight of the devices as a potential indicator of quality, noting that the ZPB 12V/15A model weighs 4.5 kg, which may suggest better materials compared to lighter alternatives. The conversation also touches on the difficulty of finding durable and functional rectifiers in the current market.
