CD Automation (Controllers, Drives & Automation) was founded in 1987 with the clear strategy of becoming the leading supplier of quality industrial automation products. Key to this success was the formation of a strong technically educated sales team. The philosophy was simple; provide product & application experts able to work in partnership with the customer to find the right solution.

In 1990 CD Automation began its development of thyristor power controllers and quickly became the worldwide market leader in using microprocessor-based technology.

CD Automation now boasts the most comprehensive thyristor power control range on the market today. The extensive range is capable of accurately controlling a wide spectrum of electrical loads up to 3000kW; from simple single-phase heaters up to complex high temperature-coefficient three phase loads.
