Product Description:
YJJ CSNK500M 500A. T rms Hall Current Sensor Is Used In Instrumentation Field
Features:
CSNK500M closed-loop current sensor is measured based on magnetoresistance effect or hall effect, and zero balance or zero magnetic flux method.The magnetic flux in the sensor core will always be controlled at zero.The flux required to balance the zero flux is equal to the primary flux through the conductor multiplied by the ratio of primary to secondary turns.The output of the closed-loop current sensor is at any time equal to the primary current divided by the number of secondary coils.This current can be expressed as a voltage across a resistance.
