Dual Power Supply

**jasonobrown** · 09-22-2007, 11:11 AM

I was wondering if there is any way to have a DC and an AC power supply connected to the pc at the same time, so that all I can easily switch from DC to AC power when I'm at home working on the pc for extended periods of time. I would obviously never have power supplied to both of them at the same time. However, it would be nice for long processes.

What I think would be an easier thing to do is to get a battery charger that has a 2/6/12 amp switch on it, and use the 2 or 6 amp position on the charger when you're working on the comp for extended periods with the motor not running. If you did it right, you could even integrate it into the car so all you would hav to do is plug an extension cord in.

Thanks for all of the great advice. I ended up just adding a battery charger and hard wiring it to the optima. Works great!

Is There anyway to prevent the opus 250/320 dc to dc power supply from shutting down the computer after a certain amount of time. Right now I have it set for two hours, but I would like to be able to leave it on indefinetly with the battery charger running. Any ideas?
