I'm sorry if I have stepped on anyone's toes here. It was my intention to be helpful to those who were considering the purchase of an autoformer. As I have noted, we have a 30 AMP autoformer and it has performed as advertised. Since installing the autoformer we no longer have issues with breakers tripping when operating our air-conditioning, washer/dryer, refrigerator, television and converter simultaneously in parks that have low voltage at the pole. When these loads are present I am at the high end of what a 30 AMP service can provide. Without the autoformer something has to be turned off. While I stand behind my previous post, I will defer to the information provided on the Hughes Autoformer web site http://autoformers.com

How Does It Work
Don't get caught with your voltage down!

At first we are tempted to say very 'well'. But this may not be the answer you are looking for!
Autoformers are used in industries to stabilize voltage and lower the operating cost of equipment. The Autoformer has 5 windings: 2 primary and 3 secondary. All models have surge and spike protection. When the unit is in Automatic and the park or input voltage is 116 volts or below, the output is 10% over the input. When the input is over 118 volts, the output is 2% over the input.

The Autoformer DOES NOT take power from the park.
It does not affect the park or input voltage, or make electricity.

What it is doing is changing the voltage - amperage relationship, lowering the amperage and raising the voltage. Since appliances run better on higher voltage, lower amperage, less overall power is used from the park, and better service is enjoyed from your RV

An Autoformer running at full output (50amps) will use 1 amp, but will cause appliances to cycle more often and run cooler. This will use less total power from the park.
