Why Do You Need An Autoformer?

Hughes Autoformers are designed to increase voltage to your RV and help eliminate low voltage damage to your appliances. Unlike a boost transformer, the 'sense circuit' in the Autoformer will adjust the output based on the load demand. For this reason you can run additional appliances on a 30-amp input. For example, a coffee pot and microwave each draw 1200 watts. Add wattage for the converter and/or a refrigerator - about 800 additional watts – and now you have 3200 watt demand. If you are only getting 100 volts from the supply, the maximum wattage would be 3000 watts. In this case, the Hughes Autoformer will boost voltage to give you 3600 watts to your RV! The Autoformer output will self-adjust depending on the demand. With the increase in the voltage to the RV (through the Autoform

How Does it Work?

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 p

Installation Procedures

Follow these easy steps to install/use your Hughes Autoformer

1. Place the Autoformer on the ground, handle up.
2. Plug the cord from the Autoformer into the RV Park electrical post.
3. Plug RV cord into the Autoformer.
4. If using an extension cord, plug it into the park post, then plug the Autoformer into it and the RV into the Autoformer.
