Order now Distributor List Contact Sales LZSR - Solar current sensors The LZSR product series 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 series 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.
