Product details

WBI412F31 converts AC input current into a load independent output signal DC voltage 0-5V,0~10V. 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. They are suitable for general applications such as fixed frequency voltage supplies etc.

The product has certain advantages of total galvanic isolation between input/output , high accuracy, low drifting by temperature, and wide temperature bearable range, etc.
