Description
The CSN Series of closed loop current sensors are based on the
principles of the Magnetoresistive or Hall effects, and the null
balance or zero magnetic flux method (feedback system). The
magnetic flux in the sensor core is constantly controlled at zero.
The amount of current required to balance zero flux is the
measure of the primary current flowing through the conductor,
multiplied by the ratio of the primary to secondary windings.
This closed loop current is the output from the device and
presents an image of the primary current reduced by the
number of secondary turns at any time. This current can be
expressed as a voltage by passing it through a resistor.
