LF505-S/SP13 Current Sensor
- Brand: LEM
- Model: LF505 - S/SP13
It adopts a closed-loop Hall effect technology. When the measured current passes through the sensor, a magnetic field is generated. The Hall element detects this magnetic field and converts it into an electrical signal. Through regulation by the closed-loop feedback circuit, the sensor outputs a signal proportional to the measured current, achieving high-precision current measurement.
