Why Osborne Transformer?
Every Osborne transformer is designed for extreme durability. Your design begins with extensive electromagnetic and mechanical modeling, then proceeds through a detailed battery of simulations. These simulations are progressively optimized to arrive at the ideal core, conductor, and other critical components. Your application will engage the expertise of a select network of the world’s finest raw material suppliers. The composite parts of your transformer will be built in strict compliance with Osborne’s exacting standards, and rigorous testing procedures.
