Osborne Transformer's name is well known among certain groups of professional electrical engineers. Perhaps it´s because they´re overexposed to high voltage; perhaps it´s because they 're confusing our transformers with plastic toys for kids. We can't figure it out - in fact we're still trying to figure out the difference between a go-bot and a decepticon. Fortunately other areas of industry keep us busy in the meantime.

Osborne has always been a modest and hardworking business. When DTE Energy began referring to an entire class of transformers as an "Osborne", we knew we had established our name. That was sixty years ago.

Today, the Osborne Transformer trademark represents the same values it has for 75 years: application specific products, design excellence and innovation.

OTC History

Osborne is an ISO 9001 certified company that designs and manufactures superior quality transformers, inductors and related electromagnetic components. In the late 1920´s, Robert Osborne began experimenting with electromagnetic core and coil assemblies. While tinkering in his east Detroit basement workshop, he developed an early mastery of the principles of electrical design. This expertise created a demand for Osborne products, and sparked a family legacy that continues into the new century.

Osborne officially opened their doors in 1932, and our business is proud of our history as socially responsible members of the greater Detroit industrial community. Osborne´s reputation has grown to include significant business partnerships within the power generation and distribution industry, the automotive industry, and the machine tool industry. We also provide design consulting and management services on projects that demand cutting edge electromagnetic component designs. Osborne´s name is known throughout the industrial and academic community as a source of world class electromagnetic designs.

Osborne´s role in these projects is to contribute specific expertise related to the design and efficient manufacture of application specific electromagnetic components.

Warranty

Few other custom electrical products can match the longevity or dependability of an Osborne Transformer. We're not boasting; that's the nature of a well designed and well built transformer. They work for a long time. It's not unusual for a properly built unit to last over 30 years of heavy industrial use. There's definitely an advantage to doing them right the first time. When you specify an application specific transformer you effectively reduce the risk of unexpected component failure. Specifying an Osborne Transformer means that you´ll have one less variable to worry about.
