Current Sensors Model CLN-50/100 Closed Loop Hall Effect Description Models CLN-50 and CLN-100 are closed loop Hall effect current sensors that accurately measure DC and AC currents and provide electrical isolation between the current carrying conductor and the output of the sensor. Features • Very fast response and high accuracy • Noncontact measurement of high current • High overload capacity • Measures DC, AC and impulse currents • PC board mount • Current sensing up to 400A peak • Solid core with aperture Applications • Variable speed drives for motors • Welding Equipment • Power supply Equipment • Measure and control system • Over current protection • Protection of power semiconductors Electrical Specifications CLN-50 CLN-100 Nominal current (I )..................................... 50 A rms 100 A rms N Measuring range......................................... 0 to ± 90 A 0to ±1 50 A Sense resistor.............................................
