Product Specification

Variable Transformer

A variable transformer, which is known by several trade names such as variac, Dimmerstat etc., is also an auto transformer, but it has a continuously variable tap so that any output voltage desired could be obtained. It is a very useful piece of equipment in any laboratory or test room. Variacs are available for 230 V single phase in various sizes. However, it is built by mounting three single phase units one above the other and coupling their spindles to a common control wheel. Variacs are rated by their current capacity which is independent of the output voltage.
