Not an auto-transformer, just an auto-disconnect when it drops below 90 or rises above 140. Limits are adjustable to >90 or <140 accordingly, i.e. to a narrow-er range if needed. Recovery voltage is also adjusted. Brown-outs can do a number on 110V devices when grid power resumes at 80-90 and stays like this for some time.
There is a plug-in single-receptacle protector on Amazon: $24, 15A, 2200W. 15A @110V is not 2200W, but close.
Or a whole-trailer protector on Aliexpress, I like this idea better: $14 with shipping, 40A. The usual doubt with this source - will it work as it should. Don't see it on Amazon.
Any suggestions?

In this area you definitely get what you pay for. I would spring for a EMS-HW30C or a EMS-HW50C depending on whether you have a 30 amp or 50 amp RV. It costs more, sure, but the extra protection is worth it.

Are you only looking to protect one item or the whole rig? Why as low as 90v?

Power companies today supply power at 120 vac +/- 5%. So you should see anywhere from 114 vac to 126 vac at your outlets if you are receiving good power. Much below 110 vac is low. 110 vac was an old standard that was raised to 120 vac many years ago.

Progressive Industries HW-30 is a hard wired 30 amp version of this with several advanced features and a remote display.. Hard wired beats plug in.
Southwire/TRC also makes one that is like the HW-30C I used the 50 amp Southwire version. Very nice.
Home was where I park it. but alas the.

Questionable devices. I also installed the PI unit and low voltage disconnects are common in many CGs. Even had 160V one time.

Almot,
Nice find! Thanks.
I do wish it were a 30 amp unit.

tuna, Check the second link. Opinion: At $14 it must be a great device. ![[emoticon]](http://www.coastresorts.com/sharedcontent/cfb/images/doh.gif "doh")

Don, you probably have 30A 110V breaker already, $14 gizmo takes 40A, should work for you - if it will work.
AllegroD: 90V is the low voltage cut-off, it can be adjusted. You don't want to run AC devices at 90 or lower. Looking to protect the whole rig.
