CS5 Series High Power Precision Current Sense The CS5 is a high power precision cur- rent sensing resistor designed with four terminals. This resistor series is distin- guished by excellent long term stability FeatureS & TCR. The Kelvin connections allow Values beginning at one high precision measurements even with appliCationS miliohm low resistance values. The CS5 series Power modules Non Inductive Design has a non-inductive copper manganin Frequency converters element inserted into a cement sealed Four terminal Kelvin ceramic case. connection Switch mode power supplies SerieS SpeCiFiCationS Series Power Rating (W)* Resistance Range (m) Resistance Tolerance (%) TCR (ppm/C) CS5 5W 1m, 2m, 3m, 4m 0.5, 1 30ppm/ * Max.current 60A at 1m CharaCteriStiCS Temperature Range -25~+150 Test Method Max.
