Four MegaWatt S-700-12 Power Supplies Running at 200 Amps 2800 Watts Output - Demo

[@YosenBMamma]

I wanted to see, the water and, the remote heads (or whatever) off the Gr/Wt/Bk leads!

[@JohnMarles]

Yosen Mamma Everybody wanted to see the boiling water but the smoking 100 amp battery cable is pretty good. The Gr/Wt/Bk leads are just going to wall plugs.

OK! Thanks, I have two amps that I use, one I use at 13v to 14v and the other I run at around 20v. Just looking for a way to use one power supply to run either amp instead of a bank of batteries and a separate supply for the other. It's always worth a try. Thanks for the great info and video.

[@JohnMarles]

If the market were bigger we would make one but right now we sell 1000s of the 12 volt units.

[@jacknifedbl]

nice!! next month ill be getting one of your 30 amp power supplies for my ham radio, it is rough to find a power supply over 20 amp w a fan that is not full of noise...

[@HAMRADIOJOE4178]

COOL, JUST BOUGHT ONE YESTERDAY THE 30 AMP ONE

[@JohnMarles]

+HAMRADIOJOE I am sure you will be happy with it.

Hi John. I have several of your S-400 supplies. They have been running non stop for 3 years in my ham shack and have served me well. My question is: Will the older 350 & 400 models parallel like the 700 series?

[@JohnMarles]

It is possible to run two S-400 or s-350 in parallel by using a 90 amp diode isolator. We sell them with instructions. The S-700-12 needs nothing to run in parallel with many another S-700-12s. www.12voltpowersupplies.us

Hi, not sure if you know, but if you are running the current directly through water you are splitting the water molecule into hydrogen and oxygen gas with can recombine explosively. I think you mistook the vapor coming off of the water as the water boiling, it was _not_ that was hydrogen-oxygen gas. Be safe man.

[@JohnMarles]

Interesting out of the box thinking and people running electricity through water can be in danger of molecule separation. However we are running the load through a large gauge Nichrome Wire which carries all the electricity from electrode to electrode thus no electricity flows through the water in a plastic bucket. The water is just used as a coolant. The smoke was coming off the 200 amp battery cables. Yuck, burning rubber. Thanks for you intelligent comment.

Can I connect two computer power supplies so as to increase overall amps from 15A each to may be 28A-30A by not disturbing voltages (12v each)? ITS URGENT

[@JohnMarles]

+Ruchit Dutt No. that usually does not work. They sense each other and one shuts down over loading the other. Since I don't sell them or know which ones you have I can only give you an educated guess.

[@MrHellouthr]

+John Marles oh thank you...actualy i wanted to power a car amplifier at home....i had two working zebronics power supplies....and instead of buying a new one i wanted to comine these

[@sarahszabo4323]

Can they be put in series?

[@JohnMarles]

No they cant.

[@sarahszabo4323]

John Marles Darn. They look great anyway. They would be great for amateur science, in my case, electrochemistry. (Think water dissociation/separation), and other electrochemical reactions. Most electrochemical reactions depend on low V high current for progression, so a switched mode power supply like this one with heavily filtered DC should be perfect! I think I might order one!

[@JohnMarles]

That sounds good.www.12voltpowersupplies.usThank you,John

[@proctoofsaryrn5108]

what can one use to test ?

[@JohnMarles]

In the video I used an 18 gauge Nichrome wire connected to car battery jumpers and submerged in a 5 gallon bucket of water. For a small load test you can always use 12 volt light bulbs. Don't turn it up over 12 volts or the bulbs will burn out.

[@OddBall1958]

Can you also make this 24v at 200 amps along with variable from say 6v to 24v? Thanks

[@JohnMarles]

No, we would have to redesign the whole power supply and in the same form factor each unit would only put out 25 amps.

[@n3rdbear]

What would you ever need this for? An artillery railgun?

[@JohnMarles]

They are mainly used for High Powered Ham Radio Linear Amplifiers. Many people connect 8 together.
