Precision Current Resistor / DC Current Shunts

The RSA series of precision current shunts from Riedon have been especially designed for DC ammeters and similar instruments. These base-mounted shunts offer current ratings from 5A up to 150A with outputs of 0.05V, 0.1V or custom options available. They utilise a Manganin® resistive element and have a standard tolerance of ±0.25% with ±0.1% parts available on request. The very low resistance values required for the shunt resistors, which range from 333.3µΩ at 150A to 0.01Ω at 5A, are provided by the Manganin® resistive elements. These RSA precision shunt resistors feature a 4-terminal design, separating the heavy duty load carrying connections from the voltage sensing terminals.
