Is this a low voltage booster?

Have a device in some RV equipment that I was told is a voltage booster. I can't find any info on it. It is a Square D 500sv43f. Is says B-4 on it. It has 30A plugs. Its sealed, says its suitable for wet locations. Any....is that what this is? Is it OK to use on my new travel trailer? Is it the same as the Hughes Autoformer?

120 volt to 12 volt transformer. Did you even try Google first?

Well, it turns out I did. And it turns out that it can be wired about 10 different ways. This is wired for 120 in/130 out.

I'm trying to figure out what this is. Is it an autoformer? I mean, if Google Gave a suitable answer I wouldn't need to ask. I just figured there are a lot of people here that are a LOT smarter than I am in electrical.

OK. Ill leave it be. Was suspicious it was not the same as a hughes, but also suspected both were a bit over the top and unnecessary. Gonna stick with the EMS.

Thanks!
