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.

We know the important role power plays in a design and that each customers’ needs vary; whether it is providing accessible product data and resources, cost effective options, or the latest products that meet global regulations. Our passion is improving the experience of the design engineer. We know that helping our customers is the core of what we do and is why we are determined on providing the best set of tools, information, and services to everyone in need of a power supply.
