Solid State Sensors Closed Loop Current Sensors CSN Series CATALOG NUMBER SYSTEM PLEASE NOTE: This matrix is intended only to aid you in identifying sensor catalog listings. It is not all-inclusive, and must not be used to form new listings. Example: CSNA111 CSN Closed Loop Current Sensor FEATURES 1 Current sensing up to 1200 amps 1 Measures AC, DC and impulse currents 1 Lowest cost/performance ratio 1 Rapid response, no overshoot 1 High overload capacity 1 High level of electrical isolation between primary and secondary circuits 1 Small size and weight CLOSED LOOP SENSORS Closed loop current sensors measure AC, DC and impulse currents over 0-25, 0-50, 0-100, 0-600 and 0-1200 Amp ranges. 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. Current Range (Peak/RMS nom.) A ±70 A/50 A rms nom. B ±100 A/50 A rms nom. C ±90 A/50 A rms nom. D ±22 A/15 A rms nom.
