The GXS Series is a LEM current sensor IC solution engineered for precise measurement of both AC and DC currents in industrial and automotive settings.
This sensor is designed to reject interference from external fields in noisy environments.
Featuring galvanic isolation and advanced signal conditioning, the device delivers accurate current sensing through the primary conductor. The primary conductor (pins 1 and 4) exhibits a relatively low electrical resistance of 1.2 mΩ, ensuring efficiency with minimal power loss.
The GXS Series is capable of measuring currents ranging from 5A to 60A up to 125°C.
