Furnace Transformers

MSI Furnace Transformer

Furnace transformers are true workhorses. We can design and manufacture a transformer to power your furnace under a wide variety of conditions. The impedance of a heating element changes with age. This requires the power output of the transformer to change as well. Our furnace transformers can be designed with multiple input and output taps to adapt to these changes.
