DIY: Power Supply for the LiPo, NiMH & nCAD 12v Chargers

[size=1.25em]Recycle, Reduce and Reuse[/size]
       
I made this Power Supply (PSU) for any LiPo, NiMH & nCAD 12v Charger(s) awhile ago. If you have an old Computer (Pc) PSU collecting dust this can be an alternative to spending the 'Arm and a Leg' they want for one specifically made for the LiPo Battery Chargers. Although the best are made from the high AMP or the highest AMP PC PSU you can find as some of the really OLD ones just don't have enough juice or amperage to power more than one charger if at all ...

This PSU also make's a pretty good desktop or bench power supply. Therefor I can also use the +5vdc line to power my RC Helicopters RX, Servos and GYRO to effectively bypass powering the motor during setup. This eliminates the risk of the heli accidentally powering up the motor during the setup procedure. Normally we would mechanically or electrically disengage the motor or use a separate battery pack to bypass the ESC when setting up our helicopters.

My Power Supply build supports 35 AMP per rail w/ connections for +12v (Yellow) +5v (Red) and Ground (Black)
... Available for my use are five separate power rails however as shown I'm only using two voltage outputs.
... The red LED indicates 'Power-on' and the blue LED indicate 'Stand-by' power.




[size=1.25em]Built using the following diagrams[/size]

I didn't add the three fuses shown in the diagram because this PSU is protected with it's own set of fuses from the manufacture. But I would recommend adding the fuses regardless as it is probably 'Good Engineering' to do so.

I should also do the right thing by mentioning my 'Circuit Wiring' image was plagiarized from this Image but I have since forgotten my source thus credit to it's owner whomever that might be.




[size=1.25em]Build one for yourself?[/size]

Rather than rewrite the book look to Google for inspiration as there are plenty of Tutorials and How-To's found there

• Google: DIY Power Supply

Although assuming good soldering and tool skills all you really need to do is follow is the above diagram, they are just that easy to build.
... The only hard part to building is finding a suitable PC Power Supply
... and NOT electrocuting yourself on the 120AC section

Golden Child has a system like that.  I saw it at one of the Sunday fun fly's at Redwood.  He seems to have a power supply from a server.  I wonder how many amps that monster puts out.

52 amps, pretty decent! and $79 for 52A is darn good IMO

Thanks guys, {LOL} Must of been 'THAT' other site where I posted this before

LMAO, this is going to be my next one ...
