The LEM HTB 50..400-P and HTB 50..100-TP are Hall effect current transducers designed for the electronic measurement of DC, AC, and pulsed currents with galvanic isolation between the primary and secondary circuits. They offer a compact design, high immunity to external interference, and a wide current rating range, making them suitable for various industrial applications such as AC variable speed drives, static converters, UPS, and SMPS.
