PC power supply?
Quick question:
Can a 12 volt PC power supply be converted for RC use? |
RE: PC power supply?
sure, many of them will put out enough for average charge needs.

RE: PC power supply?
Yes you can, althoughsome minor modifications are necessary to the PC power supply to 'lock it on'.
Caution: If you are not confident in attempting this conversion don't try, capacitors inthepower supply can be 'nasty'. http://web2.murraystate.edu/andy.bat...owersupply.htm http://www.tarmac.org.au/12%20Volt%20Power%20Pack.pdf http://customers.swcp.com/~tandberg/...pplyATX_03.htm http://www.wikihow.com/Convert-a-Com...b-Power-Supply Further information and instructions are avaiable via Google or the dedictaed web site search engines. The ATX power supply I convert a couple of years ago works great with my battery charger,I use it all the time. |

MAYBE !!!!!!!!!!! If you you know someone who is very good in electronics. Guess wrong and you may have a fire. Rich |
RE: PC power supply?
I have made about 6 of them for me and my buddies. It works fine.

I use a old Compaq laptop power supply to run my charger no modifications necessary at all

RE: PC power supply?
Some older computer power supplies will run with out modification, this is good just use the 12 volt feed, however most newer computer power supplies need minor modifications to 'lock them on' as these power supply need to detect a load to operate. That is all that is being done with the modifications outline on the internet, adding a suitble load so they will operate.
While modifications done incorrectlymay lead to a cooked computer power supply and or battery charger, it is unlikely there would be a fire. A check of what you have done BEFORE turning on the power supply, and checking the output voltage BEFORE connecting the battery charger will remove those problems. And of course positive to positive negative to negative connections as always, again check polarity with a suitable meter BEFORE connecting for the first time especially as there are a number of different coloured wires used in a computer power supply. It is not a difficult modification and it works well. Cheers David |

What about a car battery charger? Won't that work?

ORIGINAL: twoslick2 What about a car battery charger? Won't that work? As to fires when you modify the computer power supplies, very little chance of a problem. There are a number of sites on the web giving you step by step instructions on how to make the modifications, just google for them. Most will make nice power supply s for your charger. |

<div><span style="font-family: Arial; font-size: 9pt">Rodney is absolutely correct, computer power supplies are a cheap and readily available sourceof a filtered power supply. Car battery charger NO!!!, the output is to variable as a power source to operatethe sophisticated battery chargers usedfor model battery charging.

RE: PC power supply?
yep. they work great for this. basically all you need to do is to bridge the 5v rail with a load to simulate the load that a pc will have on first startup. I've got an excellent word doc that outlines the whole thing. I'd be happy to send it your way if you want it.

Sure, I would like to see it.

RE: PC power supply?
is it something you could attach here (your document), Iam very interested in this as well
