I'm thinking of putting one of my Road Rages (9V+ to 15V+) in a standalone enclosure; basically two power jacks, one 9V (in), the other 15V (out).
When connecting the power cables, I get that the outer portions would go to the positive voltage on each connection, but what about the center (-)? Since that typically goes to ground, can these two center negatives connect even though the postives are different voltages?
thanks,
Buck
Sure. Think of them as voltage taps or outputs. Ground is ground, and one output is 9v and the other is 15v. You can use them at the same time. The only limitation is how much current your load draws, i.e. your circuit doesn't draw more than the mA available.
Buck, I did just that and it works great.
