30amp Progressive EMS – Portable Version
This is the external 30 amp version of the Electrical Management System we have in our RV.
It protects your electric system against surges and a whole host of other problems that could be found in campgrounds.
This unit will tell you if the power post is mis-wired, has a bad ground, or is not putting out safe voltage for the RV.
This is the external model that you plug between the cord and the power post. It is a great option i you want to use it with multiple rvs or keep it when you sell your rv. There is a metal ring around the power cord that you can use to lock the EMS to the power post.
THIS IS FOR 30 AMP RVs ONLY
