I am working on a project that has several devices with different voltage requirements (5V, 12V and 24V). I have a 24V 15A switch mode power supply that is supposed to power my project (https://www.amazon.com/gp/product/B01CS5G8J6/ref=oh_aui_search_asin_title?ie=UTF8&psc=1)
If I ensure that my total current at any time does not exceed 15A, would there be any potential issue with hooking them up as in this image:
Googling prior to setting this up, I found several websites/forums that said this was OK, but when I tried doing this, some of my devices are heating up faster than I expected.
Perhaps there was some other issue, but I'm just wondering if maybe I need to control the current and not just control the voltage.
(Thinking about it from the voltage/current as the water-hose analogy, the devices I'm connecting to would have a certain "hose-width" and would only allow as much current as they need to flow thru them, but maybe the analogy doesn't work in this case and too much current is being forced in? I'm not sure if this question is silly, please forgive my naivety...).
So it there any problem with hooking up these two buck converters this way and then connecting them to their respective devices? (Arduinos and relays are the 5V devices (which were getting hot after a few minutes), pumps and actuators are the 12V, stepper motor drivers are the 24V devices.)
