Hughes Autoformer - 50 Amp

(Hughes 30 amp Autoformer also available)

  Hughes 50 amp Autoformer

Don't get caught with your voltage down! Huges Autoformers provide protection from low voltage damage by boosting the park voltage to your RV! The "Sense circuit" automatically turns the 10% boost on when the park power is less than 115 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. The Hughes 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 115 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.

Tech Notes

  • 733 joules surge suppression per line --1466 joules total
  • 4500 amps spike protection per line -- 9000 amps total
  • UL listed components
