Low-profile bipolar PSU/power PCB for Hammond/Bud boats?

Post by diophantine » Mon May 18, 2020 11:46 pm

I'm struggling to find a low-profile PSU or power PCB that will fit in a Hammond 1773 or Bud 423 boat (17" x 7" x 3"). This is for my Buchla 208r v1, which is ~2" deep. If there was a deeper boat available, that would be easy! But with these it leaves only ~1 inch for a PSU or PCB... the Meanwell +/-15V PSU I have is too tall to mount in that space. Same with the MFOS wal-wart PCB (shortest caps I can find are 35mm). I have a couple Frogleg Synthesis power PCBs, but they provide < .5A per rail, which isn't sufficient.

Are there any other options out there?

I know, I could put this in a Buchla boat or a wooden enclosure or a rack (I planned to put this in a rack, but then the Intellijel 4U rails become unavailable), but something like this could be very useful for other projects, too.

The Elby PSU 10 can be built pretty thin, trimmer might be highest component if you get clever with Vreg heatsinks

The Artesyn AEE00CC18-LS should work.
It is very small, outputs 500mA on each +/-15V rail and can power a 208.

I'm not a synths dealer and I'm not aware of an inexpensive Synthi secret market, please don't ask me if I know one for sale.

The frogleg pcb supports other parts with the same footprint. I've built a few using Mean Well DKMW30F-15 which seems to happily power 6u of frac. They will fit almost anywhere.

Thanks everyone!

I'll take a look a the Elby one for future reference.

The Artesyn is similar to others I've worked with, but I've always had a PCB and am not too keen on perfboarding these.

This is good to know... I looked up other MeanWell ones, but somehow missed these. I'll take a closer look, but this is probably my best option. Thanks!

For small loads you don't even need the heatsinks. There is also the PSU-8 if it is for a single boat
