A Furnace Transformer is a component in electric furnaces that is designed to regulate the voltage. Electric furnaces, of course, run on electricity. And like other electric appliances and systems, they require a specific voltage. It is used to supply power to the furnace itself. This can lower the high voltage capacity to a lower voltage output. Any furnace that uses voltage other than standard commercial power needs a transformer. The Furnace Transformer is made available by us for use in the various industries.
