LEM GXM ANC Integrated Current Sensors
LEM GXM ANC Integrated Current Sensors are for precise measurement of both AC and DC currents in automotive and industrial contexts. The sensor effectively rejects external fields originating from noisy environments. With the device's advanced temperature compensation algorithms, it ensures a high accuracy up to +150°C.
With an ultra-low primary conductor resistance of only 0.27mΩ for GXM ANC (500µΩ for GXM AN), the device minimizes power loss, achieves superior thermal performance, and includes a 20kA lightning test standard.
The LEM GXM Series supports current measurements with IPM ranging from 50A to 200A. The user can select externally settable overcurrent detection for reliable, fast, and adaptable protection solutions. The galvanic insulation between the primary and secondary sides also eliminates the need for additional insulation, which reduces both the system footprint and overall cost.
