Solid State Sensors CSN Series Closed Loop Current Sensors CATALOG NUMBER SYSTEM PLEASE NOTE: This matrix is intended only to aid you in identifying sensor cata- log listings. It is not all-inclusive, and must not be used to form new listings. Example: CSNA111 CSN Closed Loop Current Sensor Current Range (Peak/RMS nom.) A 70 A/50 A rms nom. FEATURES CLOSED LOOP SENSORS B 100 A/50 A rms nom. 1 Current sensing up to 1200 amps Closed loop current sensors measure C 90 A/50 A rms nom. 1 Measures AC, DC and impulse AC, DC and impulse currents over 0-25, D 22 A/15 A rms nom. currents 0-50, 0-100, 0-600 and 0-1200 Amp rang- E 36 A/25 A rms nom. 1 Lowest cost/performance ratio es. The CSN Series is based on the princi- F 150 A/100 A rms nom. 1 Rapid response, no overshoot ples of the Hall effect and the null balance J 600 A/300 A rms nom. 1 High overload capacity or zero magnetic flux method (feedback K 1200 A/500 A rms nom. 1 High level of electrical isolation system). The magnetic flux in the sensor L 600 A/300 A rms nom. between primary and secondary core is constantly controlled at zero. The M 1200 A/500 A rms nom. circuits amount of current required to balance P 90 A/50 A rms nom. 1 Small size and weight zero flux is the measure of the primary R 200 A/125 A rms nom. current flowing through the conductor, T 150 A/50 A rms nom. multiplied by the ratio of the primary to secondary windings. This closed loop Supply Voltage current is the output from the device and 1 15 V presents an image of the primary current 2 13 V reduced by the number of secondary 3 5V turns at any time. This current can be 4 12Vto18V expressed as a voltage by passing it 5 15Vto24V through a resistor. 6 12Vto15V Coil Characteristics 1 1:1000 turns/90 V 70C 2 1:2000 turns/160 V 70C 3 1:2000 turns/130 V 70C 4 1:1000 turns/50 V 70C 5 1:1000 turns/110 V 70C 6 1:1000 turns/30 V 70C 7 1:2000 turns/80 V 70C 8 1:2000 turns/25 V 70C 9 1:5000 turns/50 V 85C Housing Material 1 Polycarbonate/ABS blend PDFINFO p a g e - 0 6 0 60 Honeywell Sensing and Control1 1-800-537-6945 USA1 F1-815-235-6847 International 1 1-800-737-3360 CanadaCurrent Solid State Sensors CSN Series Closed Loop Current Sensors CSNA, CSNB, CSNE SERIES ORDER GUIDE Coil Current Supply Meas.
