Product Description
Product Overview
The LEM LPSR series is a closed-loop, multi-range current transducer designed for the electronic measurement of DC, AC, and pulsed currents with galvanic separation between primary and secondary circuits. It features a voltage output, unipolar supply voltage, compact PCB mounting design, and overcurrent detection. Key advantages include very low offset drift, excellent dv/dt immunity, and an extended measuring range for unipolar measurements. This transducer is ideal for industrial applications such as AC variable speed and servo motor drives, static converters, battery-supplied systems, UPS, SMPS, welding power supplies, and solar inverters.
