Table Top multi line Mod

[Relaxed5311]

So, I want to use 4 of these Amazon.com: DROK Adjustable 4.0-40V to 1.25-37V 5/12V DC LM2596 Voltage Regulator Experimental Power Buck Converter+LED Voltmeter: Electronics, in one box, with one input to the wall.

Would I just look for an ac/dc power supply that can supply the max input voltage x 4(40x4=120v)?

Would I just need a power supply that can supply something over the limit(12v) I want to set so 20vx4=80v?

Do I need something between the power supply and the 4 buck converter's to split the power to each?

I'd like it possible to be able to power all 4 converters at once if needed, I would probably just have master power switches for each one. So I can use 1 or 4 Lines.

I am not sure exactly how I am going to do this yet, but I have an idea of what I want to do. Any help making it a reality would be great, If I can get the planning done I will take pictures as I build it for everyone to see.

Hmm I think I may just need to make sure that the power supply can supply the max current (amps) that all 4 boards will use and that number is 12 amps, as long as the power supply provides the right number of volts 4.0 - 40 max, it might just work.

Have you made any progress on this???? I'm wanting to do a similar build of a table top mod with at least 2 tubes.

Here is a link to the thread I started.

I have I am still gathering parts. I got the circuit figured out and found how to power it. I will take a look at your thread too.

I am using a computer power supply with four 12 volt rails that have more amps per rail than I require. I am going to use four separate dc buck converters and actual hookah hoses. I decided to put tanks at the end of each hose too.

I had this set up with 4 passthrus and a 24 volt 10 amp source.



Passthru




Another set up was 4 LM2596s passthrus connected to the same 24v 10 amp source.
