Dongan Transformers

What Dongan Transformers does

Dongan Transformers, operating as Dongan Electric Manufacturing Company, is a privately held U.S. manufacturer of dry type transformers, inductors, lighting disconnects, and solid state ignitors. Founded in 1909 in Albany, New York as Dongan Electric Instrument Company, the firm was later acquired by electrical engineer Lyle J. Hicks, relocated to Detroit, and ultimately moved to its current headquarters at 34760 Garfield Rd., Fraser, Michigan. With 101-250 employees, the company produces both stock and custom-engineered units spanning 9 kVA to 500 kVA, all individually tested to UL and NEMA standards at its U.S. facility, with medical-grade units meeting UL 60601 specifications.

The firm serves eight explicit verticals: solar/wind power generation, commercial laundry, medical equipment, industrial automation, commercial ovens and food services, glass display and semiconductor manufacturing, commercial printing, and aircraft power. Products are engineered for demanding electrical environments, including 400 Hz aircraft ground power transformers and low-leakage medical transformers. Notable product lines include the Vanguard Series of energy efficient transformers, the Solid State Ignitor (SSI) Series for oil and gas ignition, and globally certified Lighting Disconnects.

Dongan operates an enterprise field sales model with quote-based pricing and an RFQ intake process, supported by a global distribution network and channel partnerships through NEMRA, NAED, and the Transformer Association. Quick-ship expediting is offered with delivery as fast as one week. The firm is privately held, with no disclosed parent, investors, or revenue figures.
