Variacs | Variable and adjustable voltage transformers
Variacs, which are AC power supplies, are the most popular variable auto transformers (also known as adjustable voltage 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.
