The High Current Sensor has a range of ±10 A. Current is measured with a Hall Effect sensor, which uses the magnetic field created by the current and therefore does not add a resistive element to the circuit. A metal shield over the Hall Effect chip reduces the influence of external magnets. A replaceable fuse protects the equipment and circuit.
