Schaffner acquires American manufacturer of specialty transformers

Integration will strengthen position in the US and in the international market for power magnetics

On 31 March 2014, Schaffner Group acquired from the parent company Transformer Holding LLC the subsidiaries Transformer Engineering LLC (Trenco), Magnetics Technologies LLC and Transformer Real Estate LLC, headquartered in Cleveland, Ohio.

Trenco, founded in 1937, develops and manufactures customized power magnetics solutions, primarily for customers in Schaffner Group’s strategic market sectors: energy-efficient drive systems, rail technology and renewable energies. In 2013 the US company, with 70 employees, generated around CHF 12 million.

The integration of Trenco strengthens the strategic position of Schaffner’s Power Magnetics division. Schaffner is a global partner of the leading makers of power electronic systems and has moved into the top tier of power magnetic component suppliers worldwide.
