Was in need for a power supply for a single eurorack module because when I’m developing/programming a module I don’t think it is benificial for other modules to have them powered up so often.
I had a dcdc converter in my box of goodies, input 5volt and out 12volt pos and neg, capable of supplying around 2x40mA (1 watt) which is enough for most modules.

Very cool little tool Smile

I have a Mutable Module Tester lying around, I don't use it as often as I should. (It can supply test signals, and analyse (to a degree) module output signals.)

And it is!
Lots of DC/DC converters give out a higher voltage when unloaded, this one doesn't Very Happy

And what noise this DC to DC module produces on +-12V lines? Low enough under load?
