PCB Mount Toroidal Current Transformer
The hole of PCB mount current transformer makes the primary wire can be easily put through. Our current transformers are manufactured by high grade composite cores or nanocrystalline cores, and the accuracy class can be as high as 0.05 class. We can also manufacture customized PCB mount current transformer with a variety of turns ratio and good linearity over a wide-range of primary current.
