Current Sensors Closed Loop Hall Effect Model CLN-200/300 Description Models CLN-200 and CLN-300 are closed loop Hall effect current sensors that accurately measure DC and AC currents and provideelectrical isolation between the current carrying conductor and the output of the sensor. Features • High overload capacity • Noncontact measurement of high current • Light duty industrial housing • Measures DC, AC and impulse currents • Solid core with aperture • Current sensing up to 400A peak • CLN-300: integrated bus bar • Very fast response and high accuracy 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-200 CLN-300 Nominal current (I ) ................................. 200 A rms 300 A rms N Measuring range ...................................... 0 to ±300 A 0 to ±600 A Sense resistor ..........................................
