d8b as MCU Controller 24 channels

[munkustrap]

the service manual says 100 W on 5 V
20A *5V is 100W

But maybe i do a measurement with All LEDs on.

Best regards

Ok, I believe. Glad I did mine with a big reserve then, i used old pc psu with 5v - 26a, and 12v -15a + 2 notebook psu's 19v - 6a remade to 16+ and 16- v.

Hi System32

I'm not 100% sure, but maybe Laptop switching power supplies may not be the best solution for the +/16V Domain, as also audio-parts are power with this Domain. There you will get (marginal) audio Performance reduction due to These power supplys, but if you only use the Talkback and headphone Options, it is ok.

Hi

yesterday I found the time to measure the +16V Domain

that takes 0,9Ampere, so for everyone who is interested my proposal for the customized supply:

5V / 20A
12V / 6A
+16V / 1,2A
-16V / 1,2A
+48V / 100mA
