Bridgeport Magnetics

Please note that the General Purpose (CUSTARD) Transformers should not be used for high-end audio applications, which often require special design features like low flux density. For audio applications, a full custom design is recommended to guarantee low magnetic strayfields and minimized mechanical noise.

Also, CUSTARD transformers may not be used when medical safety standards apply. For medical applications we will be happy to make a full custom designed transformer in compliance with UL60601, CSA601.1 and IEC601.1. Medical Isolations Transformers are available as standard designs from 150VA to 5000VA as shown on our website.

For Low Voltage Lighting we offer a separate standard transformer series available with or without enclosures from 50VA to 1000VA. Visit our website for details.

For Auto-transformers and Step-Up transformers please contact our factory design engineering team or use the Customer Specification Sheet for a full custom design when you cannot use the CUSTARD transformers. Using a full custom design you can specify a height to diameter ratio of 1.5:1 (Tall) or 1:5 (Flat) or anything in between to meet your specific space requirements. The most economical design uses a diameter to height ratio of 2:1.
