This thread is how to make a regulated 12VDC power supply for use with battery chargers, dischargers, etc. A good 30A+ DC power supply can be over $100, this mod can be done for a few dollars. My battery charger is dual input, I can charge froma 120VAC wall outlet or a 12VDC battery/power supply. | |

So in theory I could hook my leads up to the 12+ and 12- ports on my modded power supply and it would be the same as hooking it to a car battery? Or no? Electronics confuse me |

| I would double check the voltage with a meter first, but yes, it would work like a car battery, only it will be more stable. |

If you put your meter across the +12v and the -12v you will get 24 volts!! If your meter was not set for checking voltage, it would shut off the PS. +12 to ground should give you +12v -12v to ground should give you -12v Paul |

If you have a PS that has 2 wires shorted together to turn it on (as well as a power switch) try disconnecting the 2 wires, then turn on the power, then connect the 2 wires. The other option is a blown fuse inside the PS. Paul |

I just converted 2x HP DL380g4 575 Watt PSU`s, and run them in serial Based on descriptions on rcgroups.. Now they run bump`d up to 27v total, and still should be able to push it`s 47A max amps.. That should do the job feeding my Powerlab PL8 when it gets here |

I used a power supply from a lap top. It works great.

Anybody use a Delta electronics model dps-300pb-3b? It says max power is 300 watts, and the +12v is 18a.

Hoping someone can shed some light here, I have a 660w power supply that I want to use for my build, its a very heavy duty unit that came from a gaming tower a friend gave me. I can post a picture of the specs but I'm not in front of it atm. My question is that I know I should use a 10ohm 10watt resistor but I can only get 12ohm 10watt units from my supplier. Do you think or can you tell me how much of a voltage drop having 2 extra ohms can cause? I have to special order these and only want to do it once or it will set me back a month waiting on parts. Thanks for the input guys edit: specs are Enermax atx ges, model# eg851ax-vh(w) +3.3v 38a 240w +5v 42a 240w +12V1 14a 480w +12v2 18a 480w +12v3 16a 480w +12v4 14a 480w -12v .8a 9.6w +5vsb 2.7a 13.5w im guessing there are 4 bars in this ps? do I wire them seperatly to there own 12v output or can they be bundled together to get the most amperage possible?

Does anyone know if there is a fix because it will be rather annoying when I'm in the middle of a charge and someone wants to add their charger to my ps to charge their batteries and I loose the mah info on the balance charge I'm currently doing. Thanks Kurt | ||
