Customized Small Current Transformer
For small or mini current transformers, we can provide many options for customers to specifiy, from design to pilot run or large-scale production stage. We choose different kinds of soft magnetic cores to achieve required parameters, such as amplitude error and phase angle error. We provide different kinds encapsulations or finish types, and the primary wire shunts can be integrated. Removable or built-in busbar make the current transformer can be fixed easily by screwing. According to the secondary connecting, we can make lead wire type with tinned end or connector end, or PCB mounting current transformer.
