Toroidal Medical Power Transformers On Triad Magnetics

Due to the nature of their use, medical equipment can be extremely sensitive and have highly precise requirements that their components need to meet.

Triad Magnetics has extensive experience in manufacturing medical grade transformers. Triad’s Toroidal Medical power transformers are ideal transformers for a range of medical applications and, with more than 45 models available, we have a transformer for each of them.

Our toroidal construction medical power transformers, with dual secondary cores to allow for both series and parallel connections, maintain low leakage current, low stray fields, regulation between 0.7% and 12.3%, and low temperatures rises of only 25ºC to 55ºC.

To learn more about our Toroidal Medical power transformers — including electrical ratings, power range, secondary voltage while in a parallel connection, and secondary voltage while in a series — consult the specifications table below or contact Triad Magnetics today.
