Maconic Shunt Resistors - Knick USA

SolutionMaconic shunt resistors are the resultof many years of experience in thedesign and production of such resistors.They are carefully manufacturedusing high-quality materials. Theresistor bars are made of manganin,a special manganese-copper-nickelalloy, so that a very low temperaturecoefficient is achieved.Dimensioning and mechanical constructionare such that the resistorsonly moderately heat up until therated current is reached.The shunt resistors and associatedshunt isolators achieve a very goodlong-term stability, which guaranteesthe specified accuracy over the normalperiods of application of manyyears. Current peaks do not causeany offset or drift.Protection equipment based oncurrent measurement benefits fromthe reliability and long-term stabilityof the measurement and achievesa particularly high level of safetyperformance.Due to the low shunt voltage of60 mV, the dimensions of the shuntresistor can be comparatively small– and this is not at the expense ofmeasurement accuracy becausethe shunt isolators from Knick areoptimized for their special task.Safe measurement of currentsassociated with high system voltagesup to the kV range is also possible.The 3-port-isolated transmittersprovide a correspondingly highgalvanic isolation and are rated at3.6 kV working voltage / 15 kV testvoltage.3
