The double-conversion type re-create the power, but it's hard to say if it's a stepped-sine or true-sine output. The stepped-sine is going to have a boatload of harmonics on it.
I have a Best Power Ferrups FE at home that is double-conversion and isolated. True sine output. The Liebert GXT looks to be that type too. They can be loud, so be careful what you choose.
My big APC units at the lab are double conversion and stepped sine. Very small steps, but stepped.
