Bench Power Supply Packs a Lot into a DIN-Rail Package

We’re not sure why we’ve got a thing for DIN-rail mounted projects, but we do. Perhaps it’s because we’ve seen so many cool industrial control cabinets, or maybe the forced neatness of DIN-mounted components resonates on some deep level. Whatever it is, if it’s DIN-rail mounted, chances are good that we’ll like it.

Take this DIN-mounted bench power supply, for instance. On the face of it, [TD-er]’s project is yet another bench supply built around those ubiquitous DPS switching power supply modules, the ones with the colorful displays. Simply throwing one of those in a DIN-mount enclosure isn’t much to write home about, but there’s more to this project than that. [TD-er] needed some fixed voltages in addition to the adjustable output, so a multi-voltage DC-DC converter board was included inside the case as well. The supply has 3.3, 5, and 12 volt fixed outputs along with the adjustable supply, and thanks to an enclosed Bluetooth module, the whole thing can be controlled from his phone. Plus it fits nicely in a compact work area, which is a nice feature.

We haven’t seen a lot of DIN-rail love around these pages — just this recent rotary phase converter with very tidy DIN-mounted controls. That’s a shame, we’d love to see more.

  1. Maybe printed DIN clips for hacker projects would be the ticket. It’s true that these mounts urge a next-level neatness, but I generally find that a DIN component costs 2 to 3 times more. The rails and clips are cheap enough, but things that go on them have usually been tested and certified by every agency imaginable.

    1. clips, which as you stated are cheap you can print them if you want but having something cheap slightly cheaper isnt going to change the cost of a commercially produced din mount product

    The inexpensiveness and availability of, certainly helps.
