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.

Isolation Power Transformers
Description N/A Triad isolation transformers are power transformers for isolating equipment from direct connection to the power line. They are offered in a variety of voltages and case types. Triad isolation transformers are also offered in hospital type (designed with an MD suffix) which are designed and constructed to meet the low leakage current requirements for today’s medical equipment. The transformers are constructed with nonconcentrically wound coils. The primary and secondary are wound on separate arbors, then assembled on a laminate core side-by-side separated by insulation. This prevents electrical connection, under normal or overload conditions, between the primary and secondary windings. These hospital type units are offered with a resettable circuit breaker, providing protection from overload and short circuit conditions.
