LEM GO SMS/SME Current Transducers

LEM GO SMS/SME Current Transducers are designed to measure AC and DC currents in both industrial and automotive applications. These transducers advanced design ensures high accuracy and reliability. The GO SMS/SME current transducers provide cost-effective and compact current sensing solutions for a wide range of industries. These transducers with a small footprint and competitive pricing, offer an optimal balance of performance and affordability. The GO SME current transducers are available in the SOIC 8 package and the SMS transducers are available in the SOIC 16 package. Typical applications include small drives, Heating, Ventilation and Air Conditioning (HVAC) inverters, appliances, solar inverters, e-bikes, automotive, and industry-qualified.
