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.
