Adding EMS to your Newmar EMS/Transfer box

[tom chelbana]

Contacted TRC the maker of the Newmar EMS/Transfer system on our 18 London Aire about adding their or Progressive's EMS in front of Newmar factory system. Their response was that they would suggest adding a unit in front because the Newmar Transfer/EMS unit is over 1,000$ dollars and once it has a surge it will be burned out and would need to be replaced. But with a adding a EMS for around 300$ it would save your factory system. We will be adding a EMS system hard wired before the factory Transfer/EMS.

I have Surgeguard brand transfer switch with surge built-in. Plus progressive industries hardwired EMS in front if it. And a progressive industries portable surge only hangs on the pedistal.

I also use the portable to check the pedistal for basic functionality before going to the effort of putting the coach on the campsite.

In our 2017 Newmar offered us the new combination EMS/Transfer unit but after talking with Progressive I opted for the stand alone transfer transfer switch in production.

Then I had the Progressive EMS installed at Factory Pick UP in front of the Transfer switch like you are describing.

They also installed a Hughes Autoformer between the electrical spool & the EMS with the ability to bypass either one, in a matter of seconds, in case of any component failure.

That Hughes Autoformer is as important to me as the EMS.

When I researched Newmars upgrade surgeguard (which comes with a heavy duty transfer switch) and PI unit all of the specs were the same.
I decided on the upgrade and the Hughes Autoformer which has about twice the surge protection as both.

Don’t confuse EMS with a surge protector. EMS in the coach performs load management. Surge Guard is in the transfer switch if optioned.

I use a Hughes Autoformer with internal mount kit then it goes to a progressive internal surge protector then to my transfer switch with surge guard.

Progressive Ind. calls their units a EMS (electrical management system) but yes it's not anything close to an on board true EMS.

As NeialC posted - The Autoformer with built in surge protector & the Progressive EMS do 2 entirely different things.

Don't confuse the Progressive basic surge protector with the Progressive EMS complete system management.

The Autoformer is only correcting the voltage (both too high or too low) prior to it be read by the EMS. The Autoformer has a built in surge protector that's designed to protect the Autoformer itself.

The EMS doe not have the ability to correct voltage - it only reads it.
The reason to put a Hughes Autoformer in prior to the EMS is that any needed voltage correction is done first as the EMS would just shut the coach down if it reads too low or high voltage. Then the EMS runs a load management system that protects the coach. The EMS will run a coach check system before allowing the power to the coach.

Install both & make sure you have the ability to easily bypass in case of a failure.

Easier to call the customer service Ventana specialist number at Newmar. They probably know mare about your coach.

Congrats on your purchase. Look in your electrical bay where the power cord is located. You'll find the transfer switch in the back against the wall, most likely to your left. Look at the label on it, it should say Surge Guard or something to that effect IF it has surge protection. I didn't realize mine had this and I had already ordered the progressive industries surge protection which Newmar installed for me during my factory pickup (not hard to do on your own) and I still recommend this. I also added a Hughes AutoFormer. But that should answer your question, it's on the transfer switch. You can also login to newgle (get your account setup first) and it will tell you everything about your coach.

You can also email VentanaService@newmarcorp.com if needed but I try to find the answers myself before calling or emailing.

I always prefix my emails with my coach number when emailing, it's like your SSN. For example my email subject will be XYZABC - What did I do now.

The TRC contact stated the Newmar option Transfer/EMS system is a quality with a lot protection and is a worth while option. He said it would be a 1,000$ cost for the unit.

Still like keeping them separate in case of a failure.

The stand alone Progressive EMS has a bypass on it (not sure if the TRC has a bypass) & also carries a lifetime warranty from Progressive. They will immediately send you out a new board or even a new unit no questions asked.
Progressive is the most popular unit out there for a reason.

Either one is good & you can't go wrong either way.

Most never have a problem with their transfer switch or EMS so don't beat yourself up over it & enjoy your coach.

Yeah, the progressive EMS isn’t the same as a true EMS... however it does a lot more than a surge protector and should not be confused with that.
