Being an RVer and traveling all around the country gives you such freedom and variety, but sometimes visiting new parks means that shore power might be compromised. Every RVer needs power protection to keep their RV appliances and wiring safe from unexpected power problems and costly repairs.

Portable surge protectors are great, but sometimes we forget to pull them out of the baggage compartment to use them. During usage they are also left outside and are susceptible to theft. The Progressive Industries 50 Amp Permanent Electrical Management System is permanently installed in your coach so it is always watching out for you and it is kept safe behind locked doors. When Progressive Systems says they are monitoring, they really are – 24 hours a day. The response rate is lightning fast at 1 billionth of a second!

Progressive Industries Electrical Management System is not just a surge guard, it is a management system that gives you Multi-Modes of surge protection, L-N, L-N, L-G, L-L, and N-G, with a joule rating of 3580, and an 88,000A surge current.

Repairing broken electrical components can really be a pain, but Progressive Industries 50 Amp Permanent Electrical Management System has a modular design with plug and play parts that makes repairs simple.

The Progressive Industries 50 Amp Permanent Electrical Management System has a state-of-the-art Computer and microprocessor programmed with software that constantly assesses for all the power problems you could imagine. The EMS turns off power in any of these situations, accidental 220V, open ground, reverse polarity, open neutral, or AC frequency deviations. The Progressive Industries 50 Amp Permanent Electrical Management System is also watching out for high and low voltage spikes and instantly shuts down power if there is a drop below 104 volts or a rise above 132 volts.

Progressive Industries features a Lifetime Warranty to the original owner. Progressive Industries guarantees that their product will be free from defects for a lifetime. That is a warranty that its competitors currently do not offer.

If you are shopping around for a surge protector you will usually see a section about restart delays that are around 2 minutes 16 seconds. A/C compressors need time to wind down before restarting power. The Progressive Industries 50 Amp Permanent Electrical Management System creates a 2 minute 16 second delay when restarting the power, to protect your A/C compressor. You will know when power has been turned off because the reset indicator light will flash for 2 minutes 16 seconds then power will be restored.

Progressive has made this 50 Amp EMS, with a built in bypass switch letting you override the system and turn power back on if needed. The surge protector aspect of the EMS stays active even if you bypass the system.

The monitor on the Progressive Industries 50 Amp EMS comes with a 14’ cord that snuggly attaches to the port on the EMS. The display is continuously showing power information displaying each message for two seconds at a time. You will see voltage, frequency, error codes, previous errors and current readouts. Error codes are conveniently stamped on the unit. How easy is that!
