For over 80 years, Clary has engineered power solutions built to perform where others fail. We have continually solved high-stakes challenges with precision and purpose.
Decades of innovation… built for what’s next.
Clary began in 1939 as a high-tech manufacturer of precision aircraft components for the U.S. military. Over the decades, the company expanded into advanced technologies, including gyroscopic devices for missile guidance systems, portable computing equipment, and even mechanical adding machines.
In the 1970s, Clary pioneered the first all solid-state Uninterruptible Power Supply (UPS), setting a new standard for power reliability. Since then, we've continued to lead the industry — designing and manufacturing all-digital UPS systems trusted worldwide for their rugged performance, wide temperature tolerance, and unmatched reliability. Our systems are engineered to protect sensitive electronics from the full spectrum of power disturbances, keeping critical infrastructure running when it matters most.
