Precision Shunt, Rated Current 2000A, Standard Tolerance 0.1%

Low Thermal EMF, TCR

±20ppm/℃

Shunt works at very high current, so the temperature of surface rises sharply which will

cause the change of resistance. For precision measurement, we must choose shunts

which are with low TCR, low PCR and low Thermal EMF.

Resi launched the precision shunt series which can reach 0.1% 10% to 100% of rated

current. The maximum TCR is

±20ppm/℃ in the range of -20℃ to +120℃. Besides, the

shunt has extreme stability with low PCR and low Thermal EMF.
