Dipolar was founded in 2005 by Walter Rönnblom, now working as president for the company, who previously has worked with international marketing of industrial systems and as development manager for industrial electronics.

”We could identify a need on the microwave heating market for hightech power supplies that made it possible to achieve both energy effectiveness and integrated control possibilities.
Our aim has always been to provide high quality, better technology and energy effectiveness.”


The experiences from the initial projects, with multiple power supplies installed, where very positive.

”Our customers suddenly could see new possibilities of control system integrations.”

The power supplies are today sold to customers in US and several European countries.
