We Manufacture The Iron Cores Which Lowers Consumer Cost
Purchase Transformers With Home Manufactured Tape Wound Iron Cores.
Since we manufacture our own cores, we can offer you lower prices on transfomer products. We are one of the only companies that manufactures such cores.
Not All Competitors manufacture their own cores, since they have to hire other second party companies to manufacture the magnetic cores, the "cost to you" is a lot more than buying from TRANSFORMERS DIRECT.
Our Vertical Integration process makes each transformer AMERICAN BUILT - we build our Silicon Steel Tape Wound Cores used for each Toroid Transformer instead of buying from a second party broker.
Using CAD/CAE software and simulation equipment, our engineers develop and test a wide variety of custom transformers & other special magnetic products. The best copper wiring is used, increasing the efficientcy of the transformer and generating a lot less heat.
Within our product design and features, we final test every transformer for 15 different parameters using the latest automated test equipment.
From medium to large transformers, you can buy one(s) with a metal composition to fit your needs. Our company provides a full range of the best transformers, at prices that are cost affordable.
