Hi You can get a very good industrial 24V supply for < $40 (and maybe < $20) brand new from distribution. Comes with a 3 year warranty and has all the various protection things you would want on a supply. My claim is that you will always have 12V, 24V and 48V “stuff” running around. Having a bulk supply for each makes things a lot easier.
