autoformers for dummies (me)
Hi all, I've heard folks saying autoformers "steal" power from the campground and hence from other campers. Here is my understanding of what happens. The total wattage remains the same less abou...

Hi Triker33,
My comfort level for running the roof air is 108 volts. The cut out on the Progressive industries is 104 and the Surge Guard is even worse at 102 volts, so those devices are essentially useless to me.
I'm using a Mexican autoformer called a "Sola Basic". For voltage it has three levels of boost and one level of buck 110-->121, 100-->121, and 90-->109 volts. Buck is 135-->125 volts.
Testing on the bench showed it performed as advertised.
Real life testing showed similar boosting with between 1300 and 2995 watts of load.
Because of the way I wired the Sola unit, I can more than double the surge protection of the PI and SG units. I'm currently at 2400 joules and 40,000 amps.

A autoformer won't boost you from 110 to 120V most don't have that much boost.
If you have a surge protector with the low & high cutoff you won't be running your roof AC on lower power then it can handle.
I have had a Hughes(OK), Frank's(Junk) and now no longer available the best of them all a Power Master(very,very good)autoformers all 30AMP.
Power Master Autoformer it has 12% boost.
