WBI414F23(30A to 400A Input AC Current Converter) converts AC input current into output signal DC 4-20mA. It has adopted electromagnetic isolation principle for real time measurement of AC current from electric net or electric circuit. The output signal (voltage or current) of this transducer is proportional to the rectified average value of input AC current or reflects the input current wave.
