This is a transformer for step-up, step-down and split phase output balancing purposes. It is not an isolation transformer and offers no isolation whatsoever. The Autotransformer itself is super simple but its use gets pretty complicated. I tried to explain a bit more about it in my Blog Post on the subject.
