Introducing the World’s Only “All-in-One” RV Power Solution.
The legendary, original, and patented RV voltage booster, now with the world’s most advanced surge protection.
The Hughes Autoformer 50 amp RV power boosting autoformer (RV220-50SP) has the same performance and reliability of the original RV220-50 but now has advanced surge protection. The unit constantly monitors incoming power to protect against spikes or surges. As an extra feature the surge / spike protection module is also replaceable. In the event of a massive spike, the surge unit will take the hit ensuring your booster and more importantly, your RV is not damaged.
The Hughes Autoformer is the only U.S patented Voltage boosting solution available today. All others are imitations.
The unit automatically starts boosting 10% if the voltage drops to 113 or below. If the incoming voltage is 114 V or higher, you will have only a 2% boost. ts to 90 volts which is the minimum amount of volts for the unit.
