HPS History

Hammond Power Solutions (HPS), originally known as O.S. Hammond and Son, was established in 1917 in Guelph, Ontario, Canada by Oliver Hammond to build various tools for the foundry industry. O.S. Hammond and Son began making tube radio sets, battery chargers and other related products between 1919 and 1927.  Their philosophy for quality and success was simple: “Build the product like you were going to use it yourself.” Oliver passed away in 1925 and his four eldest sons took over the business. It was in 1927 that the company changed their name to Hammond Manufacturing; along with the name change came other transformations. At this time, the Hammond family changed their focus from radios to transformers and filter chokes for broadcast transmitters and AC radio sets.

With the start of World War II in 1939, Hammond started to build specialized transformers and reactors for military communication and radar equipment. Almost overnight, the company grew from under 50 employees to over 300 to satisfy the critical surge in demand for transformers.

 

In 2001, Hammond Manufacturing officially became two companies.  Rob Hammond headed Hammond Manufacturing, which manufactures electrical enclosures, electronic packaging, power bars and electronic transformers. Bill Hammond renamed his transformer division Hammond Power Solutions, which manufactures custom and catalog transformers and related magnetics. This reorganization has enabled both companies to pursue their strategic goals independently, providing an orderly succession to the next generation of the Hammond family and an opportunity to create increased enterprise and shareholder value.

HPS’ presence in Europe was formally established in 2013 with the completed acquisition of two Italy-based companies.  By combining these companies, HPS has expanded its European presence and broadened its product offering and manufacturing capabilities in cast resin technology.

Behind the Hammond name is a rich history spanning over 100 years.
