I want pics of the internals, and plotted charts on depleted batteries, or it didn't happen.
Kidding. What does the 100 amper with trim pot run for?
Prototype PowerMax variable 100 amper

Ignore damaged thermistor on left, now fixed. Red wires on right go to the four 40a reverse polarity fuses. External fan is on left--it blows air in. Vertical board lower middle with white wire on top--that wire is on the board where the little blue internal pot goes on the regular converters, but here there is no pot, but the white wire goes to the bottom (inside the lid) of the external knob on the lid that adjusts the voltage.
EDIT--so be careful if you take the lid off. The wires aren't very long and you do not want to yank the pot's wire off the top of that vertical circuit board (don't ask!) unless you like soldering while praying it will ever work again (mine still works :) )
Mena I don't know which ones Randy has on offer besides the three he shows, but the PM site shows a 120a one now as the biggie. Randy's site does not make clear if his version of the variable 75 is PF corrected like the regular converter 75s are.
