2.Main Features

No input saturation:Due to the use of the Rogowski principle,the magnetic core that must be used in the traditional mutual inductor principle or Hall principle is abandoned,so that the input range of the product can be very large without affecting the performance.

Fast response time:The response time can reach the microsecond level,which is suitable for fault recording in power systems.

Broad frequency response:The bandwidth range can reach more than 20kHz,which is widely used in signal detection such as complex input waveforms.

Good linearity:The linearity of the output can reach 0.2%,which can accurately reflect the size of the input signal.

High accuracy:The overall accuracy is within 1%,ensuring the accuracy of the measurement.

Small size and light weight:Compared with traditional products based on the mutual inductor principle and the Hall principle,this product is smaller and lighter under the same input range.
