Our journey in the power supply industry, which began over 30 years ago, has led to the growth of a solid Power business with design, manufacturing and distribution capabilities. The business was originally formed as Daren Electronics in 1979.

In 1998 the company was acquired by Stadium Group plc and in 2001 the group acquired a low cost manufacturing facility in Dongguan, China where a dedicated power supply production facility was established for high volume manufacturing.

A number of further acquisitions followed including KRP Power Source, Ferrus Power and Fox Industries.

In 2015 we opened a regional design centre for power products R&D in Norwich and we acquired Stontronics, a leading power supply distribution business based in Reading, UK.

In 2016 the Stadium Power and Stontronics businesses were fully integrated and renamed Stadium Stontronics. In January 2017 we acquired cable products business Cable Power Ltd and in September we acquired PowerPax UK Limited.
