A special resin impregnation protects the transformers against corrosion, reduces heat dissipation and minimizes humming. Typical applications of control, isolating and safety transformers include control circuits or PELV circuits. Multi-winding transformers are the perfect combination of control, isolating and safety transformers in a single resilient device. Control, isolating and safety transformers absorb short-circuits and ensure safe electrical isolation in the event of a fault. Eaton offers a comprehensive range of transformers that have been built and tested in accordance with IEC/EN 61558. All transformers meet the requirements of insulation class B in accordance with IEC85 and IEC16, which ensures a reliable continuous temperature of 130 °C.
