Yu Hseng offers 'Variac' style (someone called Slidac style) variable Transformers with ratings from 120V to 23KVAC - 1 to 40 Amps. Available as either single or three phase solutions

What is variable autotransformer?

    An autotransformer is an electrical transformer with only one winding. The "auto" (Greek for "self") prefix refers to the single coil acting on itself and not to any kind of automatic mechanism.  Variable autotransformer means an autotransformer can be adjusted output voltage range. (ref: Wikipedia)

“Variac”, “Slidac”, “Adjustable voltage regulator”…What’s the different??

     There are several different names for the same component

•Variac : It is a trademark name of a variable autotransformer from WWII, and become generic none for
             hand-variable autotransformers in general especially in USA)
•Slidac: Slidac is generic none of variable autotransformer in Asia region
•Adjustable voltage regulator: This is the function of variable autotransformer in some application
•Adjustable (auto) transformer: This is characteristic description of variable autotransformer

 ⇒There are also other different words for the same component: variable autotransformer
