Made in China, New, Stepup transformer.  I sell and install imported Fiber Lasers and Press brakes all over the US and this is the style tranformer we use.  In the last 2 years, I have not had any failures.  This transformer is looking for 240v in and will produce 480v out.  Of course if your input voltage varies, it will effect the output voltage.  If you only have 208 input voltage, your output voltage will be around 340v.  I have other transformers made for 208 input voltage.
