Isolation power transformers from Triad Magnetics have been designed explicitly for use in applications where equipment must be isolated from direct power connection.

Triad isolation power transformer models are available in a range of voltages and sizes, including MD suffix-designated models designed to meet the low leakage requirements found in medical equipment applications. These hospital-type isolation power transformers are available with resettable circuit breakers for increased protection against overloads and short circuits.

All of our isolation transformers feature non-concentrically wound coils, each wound on a separate arbor. The arbors are assembled, side by side and separated by insulation, on a laminate core. Triad takes these extra steps to prevent both normal and overload conditions from causing electrical connection between the primary and secondary windings.

To learn more about our over 20 isolation power transformers, view the specification table below or contact Triad Magnetics today.
