The absolute lowest voltage I've seen is 100.

In addition to the above post, an autoformer will have your appliances running with voltage that is closer to the optimal so the appliance will be more efficient.

The power is evaluated immediately and continuous. The Progressive does have a two minute delay to verify power is stable before the switch closes. Also the delay will be restarted if there is temporary problem. This prevent your air conditioner from an immediate restart if the issue is only for a split second.

Progressive take about 2 minutes to analyze the power while Southwire can do it in 10 seconds.

Far more damage is caused by low voltage than surges. I'd go to the fully featured Hughes autoformer with surge protection.

I suspect that the damage you experienced came from a loose connection and not a "surge." All kinds of things are blamed on surges but in reality they are rare.

We made our first post on this on 10/6/20 and have been doing a lot of research since then. One possibility was the hardwired Progressive EMS-HW50C. Then we started thinking about the post mounted EMS-PT50X so that we could check out the campground wiring before pulling out the extension cords.
After further research we have added the Southwire 34951 to the list.

I installed the hardwired Progressive EMS-HW50C in our 5th wheel. It analyzes the power coming in about 20 to 30 seconds.
If the power is not correct in some way it will not let it pass.
If for some reason the monitor went bad, there is a switch on the remote to let the power bypass the unit.
So far ( 3 years ) it works correctly and seems to be a great product. KEN
