Suggestions for bipolar PSU??

[JasonWickersham]

MFOS SubCommander arrived yesterday and it requires a bipolar 12v psu.
Currently eyeballing quite a few designs with this requirement, and would appreciate any/all feedback on the topic.

Thank you all!

What's the current requirement?

Mean Well DKE series DC/DC converters look like potentially interesting candidates. Might even be able to have it run off of a 9-18V pedal supply.

That I will need to investigate…


All I could find on the MFOS site:
Let’s just round it up from 64ma and call it 100ma

If you can find a traco TMDC 06-2422 for a decent price, it's 9v in and +/-12 out at 250ma/6W.
Not sure the size of the enclosure or if there's room. But a 500mA 9-12 single supply would then be compatible.
Gotta check out the modules. Brb.
Traco and meanwell have some nice ones. Could fab a PCB or probably stripboard it

Not comparing every datasheet for ripple and such but any of these should be able to take a standard 9v tap input and convert a dual 12 out with more than enough current

I believe @johnk_10 has deployed several traco modules in builds. Maybe he could provide a few tips?

Checking these out. I am sure I will have many questions forthcoming.. Looking through Newcastle’s link as well; this would be a good foray into stripboard world for me.

Enclosure is totally up in the air, buuuuutt.. I do have this guy waiting for something cool:

I just used the Aion implementation for the lowest current +/- 15V brick and did my own PCB. Super simple and no noise issues with a few different EQ and preamp modules I’ve used it with so far. Happy to share the Gerbers with anyone who is OK with a standalone format.
