GO-SME Demonstration Boards

LEM demonstration boards offer cost-effective and accurate integrated current sensing in a SOIC-8 package

Image of LEM GO-SME Demonstration BoardsThe GO-SME from LEM is a current sensor line developed to offer a cost-effective, compact solution for both industrial and automotive current measurement needs. Built on many years of ASIC design experience, the GO-SME delivers reliable AC and DC current sensing in a variety of applications including small drives, e-bikes, inverters, DC/DC converters, white goods, and onboard chargers. Its standard packaging and small footprint make it an ideal choice for space-constrained designs where performance and affordability are key.

The GO-SME integrates advanced current transducer technology to further enhance measurement accuracy and environmental resilience. Using a different sensing technique, it effectively cancels out external magnetic interference, ensuring stable performance even in noisy environments. With low primary conductor resistance (0.9 mΩ typical), the GO-SME minimizes power losses and supports continuous current measurement from 20 A to 50 A. Integrated stress and temperature compensation algorithms allow for high accuracy across a wide temperature range, while its built-in galvanic insulation reduces system complexity, space, and cost.
