Industrial Control Transformers

To meet your complete control needs, Sola/Hevi-Duty offers four series of control transformers, all of which exceed the NEMA standards. The Selection Chart can be used to identify the appropriate transformer for your application.

Sola/Hevi-Duty offers a broad range of industrial control solutions to the most demanding industrial applications. Our products exceed NEMA ratings for inrush and regulation to ensure control systems are powered correctly. Electromagnetic control components demand inrush currents up to 10 times the transformers nominal rating. While this inrush is occurring, the output side of the transformer must not fall below 85% of nominal as specified by NEMA St. 1, Part 4. Using a transformer that does not meet these ratings may cause erroneous shutdowns of downstream systems.
