Hi Guys I have a 24v motor attached to a 90w switching PSU stepping down from 240VAC.
I want to power my arduino from a 240VAC to 5vdc premade PCB.
The problem is, the way this is all configured means (Please see attached circuit diagram) I only have access to the lower portion of the circuit diagram. IE the neutral wire and switch part (housed in an external control box).
As such I cannot connect the 5V PSU PCB in parallel.
Would I be OK to connect the two PSUs in series? What considerations would be needed?
All help appreciated
