About Us

Foster Transformer Company – providing quality custom transformer manufacturing since 1937.

Our mission here at Foster Transformer Company is to fulfill our customer’s custom transformer needs by providing innovative and cost effective electronic transformers, power supplies, and electromagnetic components of the highest quality.

Our headquarters is located in the Northside of Cincinnati, one of the city’s oldest manufacturing districts which has been designated a Federal HUBZone area. Our plant currently boasts 55,000 square feet of design, manufacturing, and warehouse space. We are conveniently located at the intersection of I-74 and I-75 and is only minutes away from I-71, the Greater Cincinnati International Airport and major rail yards.


Tool & Die Manufacturing

Our Cincinnati facility also houses the Kinetics Corporation, a fully equipped tool and die manufacturer. Kinetics Corporation allows us to manufacture our own tooling, fixtures, and unique production machinery. This cuts lead times and reduces start-up costs for new programs.

With a fully equipped Engineering Lab and the close support of Engineering, Purchasing, and Kinetics, our Cincinnati facility specializes in quick turn, start-up, and low to mid volume production of custom transformers.


Expanded Manufacturing Capabilities

Our newest manufacturing facility is located in Dongguan City, China. It is less than 50 miles from the ports of Hong Kong and Macau and is within 30 miles of two international airports. This facility is registered to ISO 9001:2000 with Underwriters Laboratories and is in a 75,000 square foot building.

Equipped with CNC coil winders, automatic lamination stacking machines, core welders, vacuum pressure impregnation capabilities, and automated test equipment, our Dongguan facility is ideally suited for mid to high volume production. The addition of the Dongguan facility maintains Foster’s commitment to globally competitive prices while retaining local support our customers have come to expect.

Sometimes we have customers ask if we used to be, or are affiliated with Foster Transformers, Ltd.

Foster Transformers Ltd. was based in London, England. This company was not affiliated with ours in any way. Their product line varied through the years from parts similar to ours to very large power distribution transformers. They also manufactured transformer test equipment, particularly oil test sets used to evaluate the contamination or degradation in the oil used to insulate and cool large high voltage transformers.

Sometime in the 1970s they were acquired by AVO Corporation and in turn by Megger. The transformer line was discontinued and the insulation test sets updated and re-branded Megger. These are no longer supported, but Megger does offer new equipment that performs the same function.

We are proud to continue our own tradition of providing the highest quality transformers to meet many applications.
