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 Autoformer) the amperage demand will be lower and the overall performance will be greater. Your appliances will operate smoothly and efficiently without premature wear and damage to motors and compressors. With an operation range of approximately 94 to 125 volts input, the Autoformer will boost your RV voltage to safe & efficient levels.

Appliance failure can be costly, as well as frustrating and inconvenient. Many AC motors burn out due to higher-than-rated current draw caused by low voltage. This wasted current could be better used to operate another appliance at the same time the AC is being used. With low voltage you generally can’t run anything else without risk of damage.
