Additional Details

The LTSR 15-NP is a closed-loop current transducer that utilizes the Hall effect to accurately measure current. The measured current flowing through the primary conductor generates a magnetic field, which is sensed by the Hall sensor. The sensor output is then processed by the internal electronics to produce a proportional output current. The galvanic isolation is achieved through the use of a magnetic core. The device is designed for PCB mounting. Its low temperature drift ensures stable performance over a wide temperature range. The LTSR 15-NP is commonly used in motor control applications to provide feedback for precise motor speed and torque control. The transducer’s fast response time makes it suitable for dynamic current measurement applications.
