Closed loop current sensor

The Hall device is used to detect the primary magnetic field generated by the current in the primary conductor, and after amplification, the secondary current is generated, and the secondary winding flowing through the reverse winding generates a secondary magnetic field; when the primary and secondary magnetic fields are relatively balanced, The secondary current is proportional to the primary current, and the ratio is the reciprocal of the original and secondary side turns ratio. The closed-loop current sensor measures AC, DC, and pulse currents over a range of 0-25, 0-50, 0-100, 0-600, 0-1200A. The CSN series current sensor is based on the Hall effect and zero flux principle (feedback system), so that the ratio of the secondary side current to the primary side current is the reciprocal of the two turns ratio, and the secondary side current is output as a signal. A voltage signal can be obtained by connecting the resistors in series in the output circuit.
