It does seem bizarre to use a 12VDC to 240VAC inverer, only to convert the 240V back to 24V - but I s'pose that's "economies of scale" for you?? :-( Its crazy alright - I suppose if you wanted enough of them, to hack the things and take 90% of the secondary away would be feasible.... How does the efficiency of going from 12VDC to 240VAC back to 24V compare to going directy from 12 to 24? Dunno. Step-up is less efficient than step-down, generally. they were bemoaning the fact that it's difficult to get a laptop PSU that will simply connect to a 12VDC supply (eg, car battery or solar-charged 12V battery). Try these. http://linitx.com/index.php...16de008b78 Now your comments on economies of scale really hit home. Steve |
