The CSN Series is based on the principles of the Hall effect 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. 60 Honeywell MICRO SWITCH Sensing and Control 1-800-537-6945 USA 1-815-235-6847 International 1-800-737-3360 Canada Solid State Sensors Closed Loop Current Sensors CSNA, CSNB, CSNE SERIES ORDER GUIDE Catalog Listing CSNA111 CSNB121 CSNB131 CSNE151 CSNE381* CSNH151* Current Range Amps ±70 ±100 ±100 ±5-36 ±5-36 ±4-43 Supply Voltage VDC ±5% ±15 ±15 ±15 ±15 ±5V ±15V Coil Characteristics Turns Resistance 1000 2000 2000 1000 1000 1000 90 160 130 110 66 110 @ 70°C @ 70°C @ 70°C @ 70°C @ 70°C @ 70°C Meas.
