In a related question I'd like to know whether the power module is limited to a certain amperage, or if it will pull whatever is plugged in to it. Ie will changing my wallwart supply to 2 amps provide 2A of power, or is there a limit (in the modules circuit) on what it is able to provide?
The answer to that might help you funbun, since it might be as simple as uprating your psu.
I think you can only have one powersupply connected to the same bus. So If more power is needed two cases is required, and they can not be connected with the case connection kit (whck connects the two busses) The rack link kit can as far as i remember be used, as you can disable the 5V connection on the link. They should only share the same ground.
As for the amps, the modules will try to draw whatever they need no less no more. If the sum of the current draw exceeds the powersupplys capacity some modules will be starved, and especially the digital modules will not like that.
You can use a larger PS as long as the voltage and polarity is correct.
Good info there, thanks both - somewhat surprised that the recommended max pull is 800ma and even more so that my 3x16 with lots of digitals will remain quite a bit under that even when I add 2x O_c eventually.
I'd have thought 800ma is a conservative estimate based on that power sheet - not suggesting anyone does but it looks like it would be good for a little over 1A without much stress on it/issue.
Another thing I wondered was if the whole system could be powered off something like the rapberry pi PSU, which are relatively high amperage and provide (reasonably clean) 5v from source. I remember someone powering a system off USB and that was going to be a DIY avenue I looked at if I was exceeding pull.
After adding the ornament and crime module to my system I've started to notice that the display on the MultiFX module is blank. It is nice and bright on initial start up and then fades away. Also the cv output from ornament and crime changes at the same time.
Using grid.aemodular.com my system is pulling about 450.2mA.
