[RE-wrenches] Schneider XW+

[Jay]

Hi all

A buddy called me with the following problem. 

He was given a 5548 XW manufactured in 2019 that doesn’t work. As best as we can figure it never worked. Still trying to get that info. 
In trying to diagnose, he noticed the transformer is rated at 0-28v and 0-120vac per leg out. I have photos. 

When he feeds the transformer with 48vac it produces 480vac out. 240vac per leg. 

But it’s a 48v unit?

Anyone have a thought on this?  Is it possible that the wrong transformer got put in it?  
I know they used to make 24v units?

Thanks

Jay
