DESCRIPTION Instructions
NOTE: This unit has been replaced by the Hughes Autoformer RV220-50-SP 50 Amp Voltage Booster With Advanced Surge Protection
The Hughes Autoformer RV220-50 50 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 117 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 55-3893) or plugs into the park's power pole. 50 Amp Autoformer.

    What the Hughes Autoformer 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.
