Power Transformer (PQ, EQ, LP Core)
PQ/EQ/LP customized transformer has a larger central pole than the ordinary magnetic cores. It is suitable to be used as small size and high power transformer. This series transformer has a cylindrical central pole, featuring easy wire winding and large capacity of cooper wire. The magnetic core is made with ferrite, meeting the requirements of power transformer for reducing magnetic loss and cooper loss. This transformer has large surface area, thus of good temperature rise property and magnetic shielding performance.
