The GXN Series is a LEM integrated current sensor solution engineered for the measurement of AC and DC currents in both industrial and automotive applications. The sensor demonstrates effective rejection of external fields from noisy environments.
Advanced ambient field rejection and temperature compensation algorithms ensure high accuracy across a wide operating temperature range from −40°C to +125°C, with selected variants supporting operation up to +150°C.
The primary conductor (pins 1 to 8) features low electrical resistance of 0.85 mΩ which supports optimal performance with minimal power loss.
The GXN Series is designed to measure currents ranging from 10 to 100 A and includes variants optimized for different application requirements, from general-purpose current sensing to high-bandwidth (1 MHz), ultra-fast response applications using high-efficiency power devices such as SiC and GaN.
Integrated and externally settable overcurrent detection functions provide fast, reliable, and adaptable protection solutions. Robust galvanic insulation between the primary and secondary sides eliminates the need for supplementary insulation, reducing overall system footprint and cost while ensuring safe operation in demanding environments.
