About Us
Tortran™ is a registered trademark of Bridgeport Magnetics Group, Inc. located in Shelton, Connecticut.
Bridgeport Magnetics Group focuses in the design and manufacturing of toroidal isolation and power transformers and toroidal inductors. Nearly all of our lines employ cores made of grain oriented silicon steel strips, powder iron or ferrite.
Since no special tooling is required when winding toroidal isolation transformers or toroidal inductors, many of our customers have found that our full custom designed transformers and inductors can be less expensive than using a standard design, even in quantities as low as 100 pieces. Full Custom design toroidal power transformers are available up to 20,000 VA. For large volume requirements, we work closely with our Chinese partner to be able to offer you highly competitive prices.
