HAT600-S Open-Loop Hall Effect Current Transducer

Precision, Stability, Reliability – Master Every Ampere

HAT600-S Product Overview

The HAT600-S is a compact open-loop Hall effect current transducer from LEM. Based on the open-loop Hall effect measuring principle, it has a nominal current rating of 600A and can measure up to 1800A peak. It is designed for electronic measurement of DC, AC, pulsed, and mixed currents, making it an ideal choice for industrial control and energy management systems. With a single-channel configuration and compact design, it is easy to integrate into a wide range of applications including industrial control, automotive electronics, rail transportation, and renewable energy.

The HAT600-S belongs to LEM’s HAT series, which covers current ratings from HAT200-S to HAT1500-S, all sharing the same compact housing for easy system upgrades and replacements.
