LEM - GO-SMS/SP3 series : IC current converter with low power consumption

LEM’s GO-SMS/SP3 is an integrated current sensing solution designed to measure AC and DC currents. With good resistance to external magnetic fields and crosstalk the IC has low power consumption, compact size suitable for applications requiring Narrow Space or Low Configuration. GO-SMS/SP3 can detect dual overcurrent with a fast response time of only 2 µs. The product measures continuous current from 30 to 75A over a wide temperature and bandwidth range.   

Besides, the isolation function between main and auxiliary conductors eliminates the need for additional insulation, reducing the area and cost of the system. With high accuracy, GO-SMS/SP3 is a suitable product for applications such as small drivers, HVAC, electric vehicles, solar energy, industrial equipment, etc.
