CSN Series closed loop current sensor, measures AC, DC or impulse current, 25 amp-turns nominal, ± 36 amp-turns range, smaller housing, 1000 turn Features Current sensing up to 1200 amps Measures ac, dc and impulse currents Competitive cost/performance ratio Rapid response High overload capability High level of electrical isolation between primary and secondary circuits Industrial operating temperature range Small size and weight Typical Applications Variable speed drives Overcurrent protection Ground fault detectors Current feedback control systems Robotics UPS and telecommunication power supplies Welding power supplies Automotive - Battery management systems Wattmeters 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. http://catalog.sensing.honeywell.com/printfriendly.asp?FAM=current&PN=CSNE151 31/08/2006 Datasheet -- CSNE151 Page 2 of 4 CSNE151 CSN Series closed loop current sensor, measures AC, DC or impulse current, 25 ampturns nominal, ± 36 amp-turns range, smaller housing, 1000 turn Product Specifications Sensor Type Sensed Current Type Sensed Current Range Package Style Output Type Maximum Continuous Current Supply Current Supply Voltage Offset Current Offset Current Drift Coil Resistance @ 70 °C Response Time Coil Turns Output Nominal Operating Temperature Range Storage Temperature Range Minimum Measuring Resistance Maximum Measuring Resistance Housing Material Mounting Pinout Style Accuracy Availability Comment UNSPSC Code UNSPSC Commodity Series Name Closed Loop Linear ac or dc ± 36 A Series Connect PCB Mount Current ± 36 A ± 10 mA + output ± 15.0 Vdc < ± 0.15 mA < ± 0.6 mA 110 Ohm
