Really nice
The Suburban NT-16SE propane furnace in our RV, does not ignite when the battery voltage drops below 12.4 or thereabouts. This little converter, connected to the ingnitor board (not the blower motor) keeps it working when cold and low voltage. I set it to 12.9. It also fits nicely in a small project box from All Electronics.

More Info...
From a similar unit on eBay, I was able to determine that the 3 pots are for adjusting Under Voltage, Constant Current, and Constant Voltage. It also apparently has a fuse on in the input (15A?)
