CUI Inc

At CUI our purpose is straight-forward: power products how you want them, when you want them.
Motivated by our customers’ needs, we are focused on creating ease of access to power supply products and information that help drive an engineer's design. Our goal is to improve the way power products are purchased today and into the future.
Originally starting out as a company that sold oscilloscopes and electromechanical components, we began designing and selling power supplies as a side project. The side project grew over the years into a portfolio of ac-dc power supplies and dc-dc converters. Today we are proud to offer an extensive line of power products to our global customer base that serve the consumer, IoT, industrial, and medical industries.
