Hall Effect voltage transducer LV 25- P is used as to measure the phase voltage or line voltage. The operating range of primary voltage is between 10- 500 V with primary current of 10 mA and conversion ratio 2500:1000. And Hall Effect current transducer LA 100- P with ratio 1: 1000 is used as a current transducer that provides reliable, linear, and accurate measurements. The design diagram for the two transducers is shown below.
