Variacs, which are AC power supplies, are the most popular variable auto transformers on the market because they are cheaper, lighter, and smaller than dual-winding transformers. They also have a staggering number of applications. We carry a variety of variacs including energy-saving and industrial-strength models with different voltage inputs and form factors to suit your needs. These adjustable power supplies can be used for a number of hobbies and are very versatile. We also carry replacement contact brushes and fuses.
