Precision AC Current Shunts
-
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.

DC Current Shunts
-
DC current shunts / standards are true 4-terminal devices that precisely measure DC currents from 10 A to 10,000 A. They use special alloys in the resistive elements which are supported on an insulating base for mechanical stability. The 9230A includes special features to reduce the effects of power dissipation and associated self heating errors. These shunts are designed to operate in air at full rated current. These are the best performing, and most widely used, DC metrology shunts in the world.
