Progressive Industries' Hardwired Electrical Management System (EMS) provides full RV surge and electrical protection against all adverse power conditions.
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 include: Built-in digital readout, built-in surge fault indication, amperage meter, voltage meter, frequency meter, integrated digital readout, 3-mode surge protection, and reverse polarity protection, open neutral/open ground protection, lost/open neutral protection and AC frequency protection. Factory setting 15 seconds but can be adjusted to a 2 minute 16 seconds (136 seconds) delay for A/C Protection. Frequency Protection (Low <51Hz, High 69HZ).

Modular design for easy repair, eliminating removal of the unit. Should the software ever change, EMS owners can receive a free upgrade at no cost.

    I'm a professional Electrical Engineer and Electrician for over 45 years and I have installed the direct wired system in my last 2 motorhomes. I have seen campground voltage range from 95 volts all the way up to 160 volts and this little baby will not activate until all the preset standards are met. The best money you can spend to protect everything in your rig.
    Pros: Easy installation, Great Customer Service

    This was an easy installation. I've got it inside the compartment with my electrical cord, plenty of room. I like the ability to tighten against the wires PLUS a very heavy cable clamp, thus keeping excess tension from the retaining screws to the wires themselves. So far I have been lucky and not taken advantage of the safety features. I've only went camping with it once. I know I will feel safer this winter moving around in AZ to different campgrounds.

    Saw the voltage protection device in a seminar at the Louisville Good Sam Rally this year (2012). Since I had some problems in the past with low voltage I realized that the risk ,no matter how small was just not worth taking a chance. I chose the unit from Progressive Industries due to more detailed infromation from its display and it had a much better warrenty than other brands.My unit is the hardwired and install was straight foward and no problem . Now I just plug in knowing that no current flows into my class A coach till unit analyzes connection and it checks OK.

    Great product. I had the base model of the Progressive Surge Protector series that didn't have voltage protection or delay. I realized that I was becoming complacent in not unplugging and plugging protector alone before checking polarity, ground, etc. which was defeating those protection functions. With this model, it checks those functions and many more before connecting power to the coach and it constantly checks these safety functions while plugged in. The design also makes it easy to replace the sacrificial Metal Oxide Varistors (MOVs) in the event of protecting the coach's electrical system from a lighting strike. The only trouble I encounter with instillation instillation was the small space allowed for the current coils made it difficult to make the connections.
