The 7340 Series of 4-Terminal AC Current Shunts feature low uncertainty (high accuracy), low temperature coefficients and excellent stability. These shunts are purely resistive with extremely small values of reactance. The 7340 shunts may be used over a wide frequency range from DC to 100 kHz and are optimized for use with thermal converters.
