Description

The NT6631A-CM121-EPEC is an electronic component model known as a closed loop current sensor. It is designed to measure AC, DC, and impulse currents over different ranges, including 0-25, 0-50, 0-100, 0-600, and 0-1200 Amps. This sensor operates based on the principles of the Hall effect and the null balance or zero magnetic flux method. By constantly controlling the magnetic flux in the sensor core to zero, it can accurately measure the primary current flowing through a conductor. This measurement is then multiplied by the ratio of primary to secondary windings to determine the output current. The output current can be converted into a voltage signal by passing it through a resistor.
