Delta Transformers Enhances General Purpose Portfolio
July 13, 2026
Delta Transformers has enhanced its transformer portfolio, providing customers with two clearly defined low voltage distribution transformer solutions designed to meet a broad range of commercial, institutional, and industrial applications.
The new portfolio consists of the General Purpose Standard Series and the newly minted General Purpose Flex Series, offering customers a streamlined product selection process while delivering the reliability, efficiency, and installation features they expect from Delta Transformers. The Standard Series replaces Delta’s Commercial Series and now includes a 10-year warranty and 10kV BIL rating as standard, providing greater value and protection. Delta’s existing General Purpose transformer line has been renamed the Flex Series to better reflect its extensive customization capabilities and application flexibility for more demanding projects.
“Delta continuously looks for ways to simplify our product offerings while delivering greater value to our customers,” said Mario Mongrain, National Sales Manager at Delta Transformers. “Our new General Purpose portfolio provides a clear path for customers, whether they require a dependable standard solution or a highly configurable transformer engineered for specialized applications. By clearly defining our Standard Series and renaming our existing General Purpose line as the Flex Series, we’re making it easier for customers to select the right transformer for their application.”
The new General Purpose portfolio has been engineered to deliver dependable performance across a wide range of applications while addressing the evolving needs of contractors, distributors, engineers, and facility operators. Both series include installation-friendly features and are designed to comply with the latest North American energy efficiency requirements.
