I need to have two electrically isolated power sources.
Here are the details of the application: http://revolectrix.fmadirect.com/support_docs/item_1377.pdf page 26:
I need to make this work with a car 12V DC installation as the only power source. This should work with a current up to 70 A (max of my car alternator).
Is there something I can attach to the car's 12V installation to make two isolated power sources out of it, to power these two FMA Cellpro Powerlab 8 units?
Clarification: the isolation of the power supplies is required because the two battery-charging devices connected to them are connected to each other in series, so the (+) terminal of the first one is connected to the (-) terminal of the second one. If the power supplies would not be isolated, then they would have common (-) and effectively the (+) and (-) terminals of the first device would be shorted.
