Frequently Asked Questions


First determine: Is the park voltage over 118 Volts?

Check the park power. The unit is in by-pass over 115+1v volts. It will boost when the park power drops below 114 volts. Your Hughes Autoformer gets its instructions to boost or by-pass from the park power only. It does not read or recognize the reading in your RV. If the park power is inferior (reading below 95), the Autoformer will not have enough power to work and will go into by-pass mode (and will not boost). In this case, your unit may have absorbed an electrical surge or spike. The Autoformer is designed to absorb the damage in order to save your other appliances. If this is the problem, please return it to us for service. (Remember, freight charges will apply.) Electrical surges or spikes can occur at any time and are rarely noticed by the human eye. The cause of a spike or surge could be a power outage in a shopping center miles away. Sundays are typically   day for surges/spikes to occur because campers are unplugging their RV’s to leave the park. Please check the cord for damage and also check for a bad (loose) park receptacle if the prongs are red.

Why do I 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.
