PCB Mounting Customized Current Transformer

PCB mounting type current transformers of 4-pin or 2-pin with standard pitches can be easily installed in energy meters, test instruments and so. The most common type is one with through-hole, for which primary wire or busbar can put through. As high permeability soft magnetic cores are adopted, we can provide PCB type CT with very low phase tolerance and low current error. For different applications, DC immune type CT and zero-phase current transformers are available. We assist in custom design and can provide samples within a couple of days. The manufacturing process can be referred to as below.
