LEM enlarges the measuring range of single supplied +5 V current sensors up to 450Apk
The LZSR product family is tailored for precise measurements of DC, AC, and pulse currents, spanning from 80 to 200 ARMS, all while maintaining galvanic isolation.
LZSR current sensors boast remarkable features, including low offset drift reaching as low as 3 ppm/K, a significant improvement over previous generations utilizing traditional Hall effect chips, along with reference access, overcurrent detection output, and a +5V power supply.
While LZSR-P versions are equipped with apertures for primary conductor insertion, LZSR-TP versions integrate primary conductors for direct soldering onto printed circuits.
Leveraging Hall effect ASIC closed-loop sensors, the LZSR current sensor family delivers high peak measurements, up to three times the nominal value, ensuring dependable and accurate current assessments in various industrial applications.
LZSR sensors are particularly adapted to 70-120kW solar inverters.
LZSR sensors are extensively utilized across diverse industrial applications due to their capacity to accurately measure DC, AC, and pulse currents. Some instances of these applications include:
