Delta Electronics, parent company of Delta Energy Systems, was founded in 1971 by Bruce Cheng in Taiwan as a manufacturer of TV deflection coils, electronic components and winding magnetic components. The company quickly expanded into power supplies, becoming a global leader in switching power supplies and thermal management solutions.
In the 1980s and 1990s, Delta expanded its operations internationally, establishing R&D centres and manufacturing plants in the U.S., Europe, and China. Power supplies were the key to Delta's substantial growth in the 1980s. At that time, most transformers were large, heavy and had efficiencies of only 50% (or even lower!). The switching power supplies developed by Delta were not only lightweight but also thin and compact, with a superior efficiency of at least 60% or more.
To enhance product quality, Delta began producing switching power supplies with a surface-mount design in 1985 as the first such manufacturer in the world. Today, the efficiency of Delta’s products all exceed 90%. In particular, the industry-leading efficiency of Delta’s telecom power products exceeds 98% and the efficiency of its solar inverters is as high as 99.2%. By the beginning of the 1990s, Delta became the world’s largest manufacturer of switching power supplies, a title it still holds today.
Delta Electronics established a R&D centre in East Kilbride, Scotland, in June 1997 with the aim of building a global engineering team. This team could support local IT companies like IBM (located in Greenock) and Compaq (located in Erskine) as well as HP who had bases in mainland Europe. Starting with just three engineers, the team steadily grew as it continued to develop a wide range of different power supply units for telecom base stations, photocopiers, large format printers, to name but a few applications.
Business management of this small group was transferred from Delta Electronics Inc. to Delta Energy Systems in 2004 to build closer links to a larger design group in Europe and expanding product development to include industrial and medical applications. The team in East Kilbride are now solely focused on power solutions, such as DC-DC converters and battery chargers, for industrial electric vehicles.
In recent years the East Kilbride office has helped support the launch of Delta’s first wireless charger for the industrial market, 1kW MOOVair, in 2018 and have led the design and development of the MOOVbase and MOOVon series of wired chargers which launched in 2024.
