An autotransformer that is actually a step up transformer!
When I saw this unit advertising 230V label I figured that its simply going to be a unit with a 1:1 winding that could only output what went in and that the mfr would be too lazy to relabel it for the North America market.Sure enough when I unpacked the unit it stated 230V but imagine my surprise when I cranked up the unit from a 115V ac input and the thing shot all the way up to 260V! Meaning that it is indeed a step up transformer. Looking closely I saw that the hot wire is connected to the winding half-way up the coil so the numbers check out.Please note that this is NOT an isolated transformer so either put an isolated transformer in-front or behind it if that's how you intend to use it. You can get 500VA isolated step down 2:1 transformers for cheap under $40 on many sites. Well built and great value for money.Also as other reviewers have noted the Hot and Neutral poles are reversed on the output and I had to spend 5 minutes opening up the unit and soldering the wires around.

Works well and steps up voltage too
The dial is inaccurate, but you should always be using an independent voltage meter anyway.

A very fine variable transformer for a number of uses.
It works very well, except for the meter. The meter does not work

Great Variac for the value.
If you are looking for a inexpensive but rugged Variac look no further.

Worth every penny if digital display added
Voltmeter is inaccurate. Ammeter is needed. Digital readout much preferred.

This transformer is great... low cost and easy to use
I like the Variac because it is easy to see the voltage and also easy to adjust it. Works great!!!
