1. Summary
TH0410 is a set of nine precision AC/DC shunts of different ranges that convert a nominal input current of 20 mA ~ 10 A to 1V Small voltage, easy to access voltage high-speed sampling system or high-precision data meter, to achieve wideband or complex waveform current measurement, or used to calibrate wideband current sources, transformers, sensors, etc.
2. Features
• Operating frequency: DC ~ 1 MHz
• AC and DC difference: ≤ 30 ppm @53Hz
• Optimal phase displacement: 5 μrad
• The nominal output voltage is 1 V (other voltage values can be customized).
• The typical annual variation is typically 5 ppm and the maximum is 18 ppm.
• The 1 mA, 10 mA versions mate buffers to reduce output impedance.

Note [1]: The initial deviation is the maximum offset of the resistance value under DC conditions, usually the manufacturer's factory warranty; Higher accuracy can be customized according to user requirements, such as 20 μΩ/Ω. Note [2]: When measuring DCI with a coaxial shunt, the resistance value changes due to the heat generation of the resistor itself at different input currents, resulting in an error, and the calculation formula is: | |||||
