LEM HLSR-P Series Current Transducer
The LEM HLSR-P series is an open-loop, multi-range current transducer designed for the electronic measurement of DC, AC, and pulsed currents with galvanic separation between the primary and secondary circuits. It features a compact, low-profile design suitable for through-hole PCB mounting, single +5V supply, and low power consumption. This transducer is factory calibrated and offers high bandwidth with very low loss magnetic core, making it ideal for applications requiring precise current measurement and isolation.
