Here is a schematic from an old project. Notice that there are power buses drawn horizontally. And signals / power is supplied to the second group with vertical buses. I also label the bus lines at several places so it’s obvious what the connections are. This may not be the best schematic, but it’s one I had.Okay, I´ll make the junctions closer to the devices and more spaced out. Not completely sure about how the bus lines work. Could you send a quick sketch as I can´t seem to find anything in google?
Almost exactly! It’s not a Max supply of 4A. It’s a minimum of 4A. Current ratings work differently for power supplies. A power source will only supply the current needed by your circuit. If it’s less, then generally your voltage will drop or your circuit won’t work. So the current rating of a power supply should be GREATER than what your circuit needs.Also, for the part about the current of the motors, does that mean that if each motor draws 1A at 24V, I´m going to need a battery with a max capacity of at least 4A to power all of the 4 motors at the same time?
I assume that you meant plugging a power supply or adapter into the mains. Because 120VAC will fry your motors and be dangerous. Power supply and batteries must still satisfy the requirements of your circuits. In this case, the must supply the required voltage to the motors and also be able to supply the current requirement (or be rated higher). In your case, you’ll need a supply rated for 4A or greater.And what would be the difference to plugging it straight into power mains rather than a battery?
