RS Riedon™ Precision Current Shunt Resistors

Bourns RS Riedon™ Precision Current Shunt Resistors provide a rugged and accurate measurement over a wide current range. The resistors feature center-mounted voltage taps to simplify connection to ammeters and a Manganin™ resistive element to achieve low resistance values. The RS family, comprised of RSA, RSB, and RSC series resistors, offers a compact design for space-constrained applications requiring high current ratings. The RS Riedon precision current shunt resistors are ideal for various power applications, including solar generators, wind power, heavy industrial equipment, electroplating, battery chargers, and mining.
