Second Chance Posted August 31, 2022 Report Share Posted August 31, 2022 How many of you have and use a Hughes Autoformer? We have at least one campground we visit routinely (only option near two of our grandkids) where the voltage, during the hot season, constantly drops below 104 volts and the EMS takes us off-line. I really wished we had one this last time! Have you found the Autoformer to be reliable and perform well? Thanks!

Pat & Pete Posted August 31, 2022 Report Share Posted August 31, 2022 I honestly would not be without our Hughes . It's a 30 Amp model . Our Monaco is a 50 Amp rig , but we regularly visit 30 Amp sites . That's when the Hughes really shines . It allows us to lead a pretty normal life without too much concern . We've had it for the last 11 years . I bought it used , so I have no real idea how much older it is . It just keeps working . I will add that we always run a 50 Amp Progressive surge protector .

Is there a reason you haven't done this, or simply because you seem to need it most on a 30? I'm wondering, as I've been considering an autoformer, as well, if the 50amp version, with a dogbone to a 30amp pedestal is a viable combination.

The Hughes web site says it's fine to use a 50 amp Autoformer with a 50 amp coach on a 30 amp pedestal - they even have a YouTube video of how to do it and what to watch for.

I went with the 30 Amp because that's what we needed at the time . Then as now , there seems to be a lot more 30 Amp sites than 50 . But , I think that's changing , moving forward .

About our use on 50 Amp pedestals : In the 12 years we've been full timing , there definitely have been times when power has been out . The original surge protector we started with did it's job very nicely for the first 9 - 10 years before it burned out . I have replaced it with the same model . So far , we haven't had a single appliance go bad or shut down when on 50 Amp , other than the total power outs . Maybe we've just been lucky .

Smitty77_7 Posted September 1, 2022 Report Share Posted September 1, 2022 We recently bought a place in the Yuma Foothills. And the three to four block area around us, seems to struggle with delivering proper voltage during peak usage time. Our 45' Coach is a Heavy Electric User, and we could not run all three roof system AC's off of the lower voltage. Our previous coach we used a Hughes Autoformer, putting it inline permanently installed in the coach. So we bit the bullet and ordered a new Hughes for the new to us coach. It bumped us back up to useable power voltages, and we could run all three roof airs (And of course, other electrical loads, such as AquaHot Dual Elements, at the sometime.). One thing I like about the newer Hughes, is the module that can be replaced, IF a spike takes it out... (We'd 'toasted' a Hughes in the Yukon in either 2013 or 2014... And so we like this modular approach to damage control!). We will be mounting out Hughes inline permanently inside the coach later this year. (And our new to us neighbors, said that it had been a gradual decline in power availability - as more and more of this areas of the Foothill's were converted to manufactured homes and or stick & brick's homes... Many have made request with APS to beef up capacity...). Best to all, Smitty Quote Be safe, have fun, Smitty 04 CC Allure "RooII" - Our "E" ride for life!

rpsinc Posted September 1, 2022 Report Share Posted September 1, 2022 As an option to the portable device you bought, you may be able to have installed a buck/boost transformer that is designed to do what you are needing. And it can be left on your lot for others to use should you decide to rent it. Quote Marcel Link to comment Share on other sites More sharing options...

TexasPSDX Posted September 21, 2022 Report Share Posted September 21, 2022 When we park, 1st thing I do is plug in my Progressive Dynamics EMS. I check the voltage on both incoming lines. If low, I pull out my Hughes and plug it in. Even when initial reading are OK, I check a couple of times during hot afternoons when electric usage is high. We have only needed it a few times to boost voltage, but when we needed it, it preformed.

We have a hard-wired PD 50 amp EMS with a display inside near the distribution panel, so we have constant voltage monitoring and the protection of the EMS. My plan is to do as you do - only use the Autoformer when needed.

TXiceman Posted September 22, 2022 Report Share Posted September 22, 2022 Go inside the trailer where your main feed enters the back of the power breaker box. Mount the Hughes in the basement and set up your plugs so that you either power the Hughes or bypass and connect direct to the power panel.

That came about I think from a misunderstanding of how an auto-transformer works, which is the item at the heart of the Autoformer. I have not heard of that happening in probably 10 years or longer.

Hughes Autoformer The misfortune of the similar naming has caused a lot of confusion. An autotransformer (in this case "auto" meaning self rather than automatic) is a transformer that uses a single winding and core with multiple taps. Autotransformer Wiki The Autoformer is a different animal and does not use that electrical configuration.

oldjohnt Posted September 26, 2022 Report Share Posted September 26, 2022 Good mornin Second Chance; FWIW as I have no specs data or wiring diagrams, it's my understanding the Hughes product IS NOT what I call a Tap Changer method of voltage regulation in which case over and under voltage was automatically corrected by switching the secondary over to different taps off the transformers primary IE TAP CHANGERS. One OTHER method of voltage regulation involves using a transformers heavy iron and magnetic material TO STORE ENERGY IN THE MAGNETIC FIELD which can be used/discharged in cases of low INPUT voltage (like a brownout) to boost its OUTPUT voltage if needed. As Energy = Volts x Amps x Time and if the transformer stores ENERGY in its heavy magnetic material field, if the INPUT voltage were to drop the transformer could draw from its stored energy and/or draw more INPUT CURRENT to maintain the correct OUTPUT VOLTAGE. If ? thats how the Hughes works (not saying yes or no) one could consider it to be using (call it stealing if you like) more CURRENT in order to raise/maintain voltage at the Hughes owners site ??? I would NOT consider it as taking/stealing DIRECTLY from your neighbor, but taking it FROM THE PARKS DISTRIBUTION........HOWEVER drawing excess current can cause voltage drop AT YOUR NEIGHBOR and rest of park.. A sematic problem perhaps but the laws of physics prevail and Energy = Volts x Amps x Time and its possible to draw more current in order to increase voltage in a device but is that how a Hughes works ?????????????? DISCLAIMER i have no specs data or wiring diagrams so I DO NOT know if the Hughes works like that. IM ONLY SAYING its possible to draw MORE CURRENT (from the park maybe steal/drop/lower neighbors voltage if you like) in order to maintain output voltage at the Hughes owner site If anyone knows exactly how the Hughes works PLEASE LET US KNOW. I do think it could draw more current thereby cause voltage drop at other sites in the park ??? John T Retired yet ever curious engineer open to learn.
