what is the output pressure, and is it adjustable?
Marshall Excelsior MEGR-253 Two-Stage Automatic Changeover Regulator
LP Regulators
I am looking for an automatic change over regulator to connect to 100 lb tanks, and go from high pressure to intermediate pressure-less than 50 lbs output. I already have a low pressure regulator set up on a manifold for my house

The Marshall Excelsior MEGR-253 Two-Stage Automatic Changeover Regulator is engineered to provide a fixed low-pressure output, typically around 11" W.C. (~0.5 PSI), which matches standard RV-style regulators. This makes it unsuitable for applications that require an adjustable intermediate pressure below 50 PSI for connecting to a house manifold. For your requirements, a high-pressure automatic changeover regulator with an adjustable outlet pressure—such as the MEGR-1620 model—would be necessary. Unfortunately, we do not carry the MEGR-1620 model at this time.
