An isolation transformer is a custom transformer placed between the power supply and other parts of the circuit which doesn’t provide a metallic conductive path between circuits, instead linking two circuits electromagnetically. This could be required in a power supply for medical equipment, or other high integrity applications, particularly in military systems, to prevent any leakage from the AC power system into other systems (a patient, for example).

Isolation transformers are custom transformers which are typically place in line in a circuit which requires modifications to output such as eliminating distortion to other components in the circuit.

Dufrane’s Isolation transformers are custom transformers which may require special designs such as fitting with a specific space envelope, and options may include a custom enclosure, multiple taps, connections, weatherproofing, etc.
