Arduino supply voltage

[brian86770]

you can add buck regulators if you want multiple voltages from one supply…!!!
just don’t exceed the total wattage from your supply output…!!!
the one Bryce posted above has a 60 watt total wattage output… !!

this is one of my supply units.

My power supply

[IMG202102020126161] this is powered off two 20 Ah 12 volt AGM deep cycle battery’s in series.to form 26.8V volts at full charged battery power…it is a D.C adjustable regulator…multi tapped…so basically is all step down…or “buck” type system … it has an 6Amp 35 v linear supply feeding into an mmpt 60 Amp smart regulator so it is well maintained on the input regulation. the input terminals are at the center of the supply and can be powered by any supply that you may want to use 30 volt …
