Variable Isolation Transformer are different from a variable transformer, like a variac. Isolation from mains gives greater safety. Teardown of a variable transformer, which provides a variable voltage and isolation. Single phase 1x250V @ 3A.

I give a short introduction to the differences between autotransformers, variable autotransformers and variable transformers. I show my collection of 7 variac transformer / variotransformer in the range from 1x260V @ 2A to 3x400V @ 25A along with a 3x400V 10kVA isolation transformer. 3x400V @ 13A Variac demonstration with data monitor: https://www.youtube.com/watch?v=PqeLLLZTBb8 You might wonder
