Product Introductions What Is A Variable Transformer? A transformer consisting of only one coil which is shared by the primary and the secondary side of the circuit is known as an autotransformer. A variable autotransformer is known generically as a Variac, the ratio of the primary to the secondary windings is variable, which means that the ratio of the secondary voltage to the primary voltage is variable.
