TH0400 Precision Coaxial Shunt

TH0400 is a series of 14 high-precision coaxial shunt devices engineered for accurate current-to-voltage conversion. Designed to support measurement ranges from 1 mA to 100 A, these shunts convert nominal current into a precise 1 V output, enabling wideband and high-accuracy current measurement. The TH0400 series is suitable for calibration laboratories, power measurement, wideband current source calibration, and precision testing of transformers, sensors, and metrology equipment. Its excellent stability, low temperature coefficient, and advanced coaxial structure ensure high reliability in demanding industrial and scientific applications.
