Control transformers are generally used when a circuit requires constant voltage or constant current with a low power rating. Various filtering devices, such as capacitors, are used to minimize the variations in the output. This results in a more constant voltage or current.

Dufrane’s control transformers are typically small custom transformers which are either build to print or designed to meet your stringent requirements.

Whether it’s size or envelope restrictions, sealing, multiple taps, mounting configurations, enclosures, potting, high temperature, humidity, vibration, shock or other requirements we can handle from the simplest and smallest of custom electromagnetic solutions to the most complex.
