Micro Air
Hi, just looking for input from people that have them on their effectiveness. I am thinking of getting a portable genny for the 5th wheel for those times that I need an AC and don't have power. I ha...

My tests of the autoformer show these results.
The back yard experiment was at my brother's cottage with a 50 amp outlet. It is in a resort area fed by an ancient grid connection. The autoformer would cut in perhaps 1/4 second (or less), before the airconditioner motor even finished getting up to speed.
Once I added the MicroAir, the autoformer did not cut in any more but that meant the air conditioner ran at a barely acceptable 107 volts, rather than the 112 on the autoformer. The motor speed was lower as well.
I did find a work around by fudging the cut in voltage for the autoformer upwards from the factory setting to 113 volts.
The sequence now appears to be fan start, time delay, compressor start, autoformer cut in. Before it was fan & compressor start with almost instant autoformer cut in.
My view is the MicroAir is no substitute for an autoformer. It does NOTHING to raise the voltage.
Running from the generator the microair seems to make no difference. That is with the Magnum generator input throttled to 23 amps (which is the output from the generator).
