GO 20-SMS

GO 20-SMS is a GO-SMS series, LEM integrated current transducer solution designed to measure AC and DC currents in both industrial and automotive applications. The differential sensing technique allows the transducer to reject an external field coming from a noisy environment. Proprietary stress and temperature compensation algorithms are implemented in order to achieve very good accuracy over wide temperature range. The primary conductor (pins 1 to 8) has a very low electrical resistance of 0.75mohm (typical), which enables excellent performance at low power losses. It is approved by IEC 61800-5-1: 2007, IEC 62109-1: 2010, IEC 62368-1:2018 (supersedes IEC 60950-1: 2005), UL 1577: 2014, UL 62368: 2019. Applications include small drives, HVAC inverters, appliances, solar inverters, automotive & industry qualified.
