Not completely sure how to categorize this inquiry, but I'm interested in an AC - 12v DC converter that will allow me to safely power all of my car components in the house using mains AC as the ultimate source. The interest here is in testing ALL components to make sure my setup works under simulated 12v battery connection before installing it in the car.
Here is what I wish to power under simulated car battery condition, in the house:
1. P1900 (to which is to be connected an Intel Mac Mini and VGA-RGBS scan converter. The Mac will have connected to it a USB hub, USB screen coordinate converter board, USB wireless keyboard dongle, and USB audio adapter)
2. Factory NAV system, which includes RGBS monitor and 6-disc CD changer
3. Three 12VDC relays
My interest is in finding an AC-DC converter that delivers safe, sufficient power to the above setup, in the correct voltage-- That which basically acts like the entire system is connected to my car's battery. I cannot stress enough that this needs to be a safe power supply, as the components to be powered are far too expensive and valuable to risk blowing.
Thanks for your thoughts on the matter, everyone.
What if you were to buy two lantern batteries from the local sporting goods store. Wire them up in series so that you have 12 volts? They may not last long, which would be the only problem. You might be better off trying to find a 12v battery from a "Power Wheels" vehicle. They'd be cheaper than the $100 supply the above link is suggesting, and I'm sure they'd power a computer for hours.
Thanks very much for your help in this matter, all-- I hope not to be too much of a noob in this regard-- I'm just really concerned about protecting the components I need to work with. They constitute considerable $$ !
I'll likely go the route of PC power supply. I have one on hand already, and with some minor modification it appears such a thing will suit this need perfectly (and inexpensively, to boot-- A great thing if you haven't ample financial reserve, such as I! ).
