The LEM LF 205-S is a closed-loop (compensated) current transducer utilizing Hall effect technology. It is designed for the electronic measurement of DC, AC, and pulsed currents with galvanic separation between the primary and secondary circuits. Key advantages include excellent accuracy, very good linearity, low temperature drift, optimized response time, and a wide frequency bandwidth, making it suitable for industrial applications such as AC variable speed drives, servo motor drives, static converters, battery-supplied applications, UPS, SMPS, and welding power supplies.
