I am looking for a power supply that can deliver 13.8V - 14V with 10-15Amps for a Hobby battery charger. Ordinarily, a 12V lead acid Car batter is used. I would like to use a power supply that I can plug into the wall.
The Computer power supply can be altered a bit, but it only gives 12V, and the current is low.
I am looking for a power supply that can deliver 13.8V (recommended by the charger) and like 10-15A current. This must be a DC regulated linear voltage with no fluctuations...like for a computer power supply.
Are there and schematics for a DIY circuit? or can the PC power supply be altered to give the higher voltage + current?
The hobby industrial has a 13.8V, 10+ Amps power supply for chargers but there retail for $150 USD...which I find over priced in my opinion.
Any help would be appreciated. Thanks.
