View Full Version : No AC/DC converter

I found it interesting that my Newell did not come with a converter. From the posts I have read on this board, I do not remember reading of a converter being used. Of course the battery charger provides the juice, so maybe a converter would be redundant. All my previous motorhomes had a converter/charger so I guess I thought they were standard equipment in RV's.
What prompted this question is that I just installed a http://www.bogartengineering.com/2020.htm
battery system monitor. I intentionally discharged the batteries so I could watch the volts and amps changes as the battery charging process took place. As the system went into the float mode, you could see the volts go to 13.4 & the amps to a -.2 to +.2.
My question is How does a float mode work when additional demands are added to the battery/charger. If a converter was used for the dc load, then the charger could be left alone to just maintain the battery?

Any thoughts appreciated!

Gordon,

On mine, the charger will go into charge mode once the batteries drop below the charge point. I do see some cycling up and down of the 12v system when this is going on.
