This product is the TFY-CSB-KZL200 current sensor manufactured by Ningbo Taifengyuan Electric. It is a high-precision current measurement module designed based on the tunnel magnetoresistance and closed-loop operating principles, capable of measuring currents of various waveforms such as alternating current, direct current and pulse current. It has a rated input of ±200A and a maximum measuring range of ±240A. Featuring high accuracy grade and fast response speed, it boasts a zero-point temperature drift of less than 0.1mV/℃ and can operate stably within the temperature range from -40℃ to 85℃, making it suitable for industrial high-precision current measurement scenarios.
