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. http://catalog.sensing.honeywell./printfriendly.asp?FAM=current&PN=CSNF661 31/08/2006 Datasheet -- CSNF661 Page 2 of 4 CSN Series closed loop current sensor, measures AC, DC or impulse current, 100 A nominal, ± 150 amp range, offset pin, 1000 turn Product Specifications Sensor Type Closed Loop Linear Sensed Current Type ac or dc Sensed Current Range ± 150 A Package Style Thru Hole PCB Mount Output Type Current Maximum Continuous Current ± 150 A Supply Current ± 10 m A + output Supply Voltage ± 12.0 Vdc to ± 15.0 Vdc Offset Current < ± 0.2 m A Offset Current Drift < ± 0.5 m A Coil Resistance @ 70 °C 30 Ohm Response Time < 0.5 µs Coil Turns Output Nominal 100 m A Operating Temperature Range -40 °C to 85 °C [-40 °F to 185...
