WBI221LY05-25(DC Current Transducer Hall Effect) adopts the Hall Effect to measure the AC and DC current of the power grid in real time. Using precision constant current technology and linear temperature compensation technology, DC Current Transducer Hall Effect is converted to standard current output, and the characteristics of AC/DC current general-purpose, strong overload capacity and high isolation.
