TH0400 Precision Coaxial Shunt
Introduction
- TH0400, a series of 14 various ranges precision coaxial shunts.
- TH0400 can work in the DC ~ 100 kHz frequency range, converting 1 mA ~ 100 A nominal current into 1 V small current.
- DC ratio accuracy: 20 ppm;AC/DC difference: 20 ppm; phase displacement: 5.
- It is suitable for calibration of AC/DC high current source, current sensor, DC shunt, and other occasions where current needs to be measured precisely.
Features
- The nominal voltage is 1 V, can measure current by directly matching high-precision voltmeters or other measurement instruments.
- For 1 mA, 10 mA and other high resistance current shunts, combine with the model TH0600 to avoid errors caused by wire connection or input impedance drops of digital meters at high frequency.
- Compared to 0.5 V, 0.8 V and other voltage value, the 1V nominal voltage has a higher noise ratio, easier current conversion, faster error calculation, and accords with the 1-2-5 sequence principle of modern measurement.
- Precision components and production processes ensure the resistance value stable, the typical resistance change value is ±5 μΩ/Ω in 1 year, and the maximum resistance change value is ±16 μΩ/Ω in 1 year.
- Good heat dissipation, lower temperature coefficient and self-heating power factor ensure a good stability.
- Small phase displacement between the input current and the sampled voltage, the phase displacement is less than 0.0015 ° even at 1 kHz. This feature is critical for the measurement of non-sinusoidal and wideband signals, applied to analyze power quality and calibrate digital power meters.
- The capacity of loading current and withstanding current impulse is limited, but you can use a set of shunts to obtain a wide range of current measurement.
