A name that stands for
quality, precision, and performance

A Tradition of Quality Since 1963

A tradition of quality and precision began in 1963 when Wilmore Electronics launched its business focused on designing and manufacturing high-performance flight-quality dc-dc converters for space programs. Over the years, Wilmore expanded its capabilities to offer a robust product portfolio of DC-DC converters, DC-AC inverters and power supply products.

In about every environment and application, whether used in secure technology facilities, high-speed transit, transportation, utilities, energy or even in outer space, Wilmore has established a solid reputation for quality and performance. As a matter of fact, we have shipped hundreds of thousands of converter and inverter products, many of which are still performing like the day they were purchased after 20 years of continuous service.

Today, Wilmore operates two modern production facilities in North Carolina and provides state-of-the-art industrial power supplies to customers across the globe. When you call us, you can expect to talk to a live, highly qualified  team member ready to answer your questions, help with custom design requests, or to make sure any in-stock  product is shipped promptly.
