LKSR Current Transducers

LEM LKSR Current Transducers are comprised of high-precision current sensors designed for the accurate measurement of small DC, AC, and pulse currents ranging from 1.5Arms to 50Arms nominal, all with galvanic isolation. These sensors ensure reliability with key features such as low offset drift for stable, high-accuracy measurements, integrated primary conductors for simplified design and enhanced performance, and a wide operating temperature range from -40°C to +105°C.
