The LEM LPSR series are closed-loop, multi-range current transducers designed for the electronic measurement of DC, AC, and pulsed currents with galvanic separation between primary and secondary circuits. These transducers offer a voltage output, unipolar supply voltage, and a compact design for PCB mounting. They feature very low offset drift, excellent dv/dt immunity, and an extended measuring range for unipolar measurements, making them suitable for various industrial applications including motor drives, UPS, SMPS, and solar inverters.
