Progressive Industries' Portable Electrical Management Systems (EMS) offer quick and easy RV electrical protection with surge.
Whenever electrical power falls below 104 volts or rises above 132 volts, the EMS automatically shuts down power to the RV.

Once the electrical power rises above 104-volts, or below the 132-volt level, the time delay indicator flashes for the preset time and then automatically restores power to the RV. Features 53-mode surge protection, reverse polarity protection, open neutral/open ground protection and AC frequency protection. 2 min. 16 seconds (136 secs.) delay for A/C protection. Unit is designed for outdoor use, is both weather resistant and thermally protected. Built in digital readout voltage meter, frequency meter, surge fault indication, amperage meter.

Integrated information panel: Scrolls continuously through all of the power source information: voltage, current, frequency, error codes, and previous errors. Each reading is displayed for 2 seconds. Includes lock bracket which allows the user to secure the unit to prevent theft.

    Great addition to the saftey side of camping. Plug it into the power pole before plugging in the unit then no more worries of whether there is enough power or too much, you're covered.

    Having been a seasonal 2012 at a park with questionable power, word from another seasonal, I ordered this unit. While other seasonal campers lost refrigerators, microwaves and other electronic equipment, I only lost power because of high, low or surges. I would rather lost power than equipment.

    After much debate, I finally settled on this product. It is very easy to use; simply plug and play. The attached tab makes securing the device a simple task as well. I also appreciate that this product is manufactured in the U.S.

    This device would not allow power to my coach when I plugged into a campground in the Denver area. It correctly showed open ground with the code flashing on the box. I watched the RV park service guy open the power box and saw that the ground wire wasn't connected to ANYTHING but the box itself. They had to install a ground rod for the antiquated box to work....EEEE! I shudder to think what might have happened to my RV electrics without this box protecting the coach. It was also VERY helpful to have the code flashing on the box to make my point with the RV park that it was THEIR equipment, NOT mine, that was the problem. (I am a woman, therefore I CAN'T know about scary electrical stuff, eh?)

    Have had the unit for only 3 weeks, plugged in constantly on its slab on the side of the garage, 30 amp outlet. I like the technical date it gives me. Is what I was looking for totally. Can't say much more at this time. Hope it works for a long time. Hope the warranty isn't too hard to warranty if and when it fails. Nice product, providing what I need to protect my RV.
    Pros: Easy installation, Peace of mind
