Variac Products

VARIAC Variable Autotransformers - Distortion free, efficient, durable and accurate variable autotransformers for controlling ac voltage control. Typical applications include: heat output, light intensity, motor speed, and the outputs of various power supplies. The VARIAC is available in hundreds of standard versions to satisfy line frequency, voltage, and phase requirements, load size, mounting demands and enclosures. They can be supplied with motor drives, ball bearings, and in ganged assemblies to increase basic line-voltage and load-current ratings. It is also available in militarized models for 400- hertz operation.
