These values allow for increased accuracy in current meter shunt applications for industrial and consumer single- or multiphase energy meters. With a tolerance of 5.0 %, the new resistor provides power companies with more accurate data to determine customer usage and to adjust billing terms.
The WSMS2906 features a five-terminal connection design and an all-welded construction that contributes to its superior electrical performance. The resistor offers very low inductance values of < 5 nH and a low thermal EMF of < 3 µV/°C. The device is lead (Pb)-free and RoHS-compliant.
Samples and production quantities of the new meter shunt resistor are available now, with a lead time of eight to 10 weeks for larger orders.
