High Frequency Current Transformer

Our high frequency current transformer is designed for the secondary current conversion. It has great voltage separation ability and insulation property, and the applicable frequency range is 20kHz~50kHz or even higher. The sensitivity is 1V/A, and this value can be doubled by the application of two coils. Additionally, our product allows PCB installation mode. It is applicable in many fields, such as switch feedback, tripping protection, circuit overload protection, load drop protection and others.

Our high frequency current transformer can convert high primary current into small secondary current for the purpose of protection, measurement and others. It is very stable, and can stand pretty high primary current. Meanwhile, heat and electromagnetic force generated by pulse current are also tolerable. When the power system fails, this transformer can provide the relay protection device with information of fault current.

Huaxin is a China-based high frequency current transformer manufacturer and supplier. Apart from transformer, our company also offers amorphous / nanocrystalline core, amorphous metal, silicon steel core, and more.
