50 Amp Autoformer 


Don't get caught with your voltage down! The Autoformer provides protection from low voltage damage by boosting the park voltage to your RV! Our Sense circuit automatically turns the 10% boost on when the park power is less than 117 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! 1 per box.

Avoid brownout damage by boosting the park voltage to your RV. 50 amp Autoformer has increased capacity to 12,000 watts, with a fully automatic 10% boost when needed. Internal transformer increases volts and lowers amps, while sophisticated circuitry monitors power levels and boosts if power is less than 117 volts. Includes park power diagnostic light, as well as boost indicator lights for both lines, spike and surge protection and polarity and ground test functions. Weatherproof.

The installation kit for the autoformer is sold separately and is listed in the pricing table below.  In addition, a link to the 30 Amp autoformer is also in the price table.
