Riedon of California has announced current-sensing shunt resistors from 1A to 10kA. The RCS, RSH, RSI, RSJ, RSL, and RSN series of precision shunt resistors have four-point Kelvin connections and go as low as 5μΩ for the 10,000A 50mV RSL-10000-50. Copper-nickel-manganese Manganin alloy is used for temperature stabuility, and standard tolerance is 0.25%, with some series offering ...
