Product Description

H Class Medical Isolation Transformer Epoxy 50/60Hz Copper Coil


1.Medical isolation transformer is a professional IT system isolation transformer developed for medical places. The transformer is seamlessly wound with high-quality cold-rolled silicon steel strip. Because the iron core has no air gap, it reduces the induced vibration noise of the iron core and reduces the buzzing during operation.
2.Due to the small iron loss, the winding has good heat dissipation on the iron core with lower temperature, and the temperature rise is low; the transformer iron core has no air gap, the winding is uniform, and the magnetic interference is small. This structure makes the magnetic leakage and electromagnetic radiation small, and no need to add Shielding can be used in electronic equipment and medical equipment with high electromagnetic environment requirements, and the electrical efficiency is as high as 95% or more.
3.Small size.
