WELCOME TO ATC POWER SYSTEMS
ATC Power Systems was established in 1981 by Joel Bedell with a mission to design and manufacture high-performance military power supplies and custom power converters tailored to the rigorous demands of the military sector. In 1982, Larue Renfroe, founder of Assurance Technology Corporation, provided critical support during ATC Power's formative years. This collaboration marked the beginning of an interdependent partnership between the two companies.
After four decades of keen, insightful leadership, Joel Bedell has retired, having made a profound and lasting contribution to the companies growth and direction. Larue Renfroe now serves as CEO and President, continuing to guide the company's strategic direction along with our General Manager and key personnel's 131 years of combined experience.
ATC Power Systems and Assurance Technology Corporation continue to demonstrate strong performance in a dynamic market. We are strategically expanding our investment in advanced manufacturing technologies to enhance efficiency, support growing customer demand, and maintain consistently high product availability.
