The Hughes Autoformer RV2130 30 Amp Voltage Booster has solid state reliability with no moving parts for quality you can count on. Autoformer provides protection from low voltage damage by boosting the park voltage to your RV! "Sense circuit" automatically turns the 10% boost on when the park power is less than 116 volts and turns it off when the park power reaches 118 volts. Built in grounding continuity test offers protection against damage from open ground, open neutral or reverse polarity - if the light isn't on, do not use the power source! Installs into your RV electrical system (with the optional installation kit 55-3982) or plugs into the park's power pole. 30 Amp Autoformer.

Autoformers are designed to stabilize voltage and lower the inefficiency of equipment. 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 (30 amps) will use 1 amp, but will cause appliances to cycle more often and run cooler.

Hughes Autoformer 30 Amp Voltage Booster

Follow these easy steps to install/use your Hughes Autoformer

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

Although not preferred, you can lay the Autoformer on its side to place into a well- ventilated compartment.

Installation kits are available to install 50 amp units into your RV's ventilated compartment.

When the park power is below 116 volts the Autoformer will boost until the park power reaches 118 volts, then it will go into standby. This procedure will be repeated over and over. The Autoformer reads voltage only from the power source that your RV is plugged into. It does not read anything inside the RV.

The small holes below the cord and plug are for condensation drainage. Please ensure that these remain open and are not blocked in any way.

Please use the Autoformer as it was designed. Do not set upside down or use it for any purpose other than intended. Do not seal holes or edges with silicone or any other material. To do so will void your warranty. Removing the lid or making any alterations to the Autoformer will also void your warranty.
