Product Description

1. Summary

TH0410 is a set of nine precision AC/DC shunts of different ranges that convert a nominal input current of 20 mA ~ 1 0 A to 1 V Small voltage, easy to access voltage high-speed sampling system or high-precision data meter, to achieve broadband or complex waveform current measurement, or used to calibrate broadband 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.
 

3. Applications

☆ Set up a broadband current measurement system

TH0410 can be used with broadband current source, broadband standard voltmeter (such as TH2000 vector voltage analyzer), etc. to form a broadband current measurement system, which is used to measure broadband current signals, calibrate broadband current sources, broadband ammeters, etc.

☆ Set up broadband power precision measurement system

TH0410 can be used with high-frequency V/V conversion standard and TH2000 vector voltage analyzer to form a broadband power/energy precision measurement system for measuring broadband power/ Power signal, calibration of broadband power source, broadband power meter, power analyzer and other equipment.

 

• Build a broadband instrument transformer / sensor measurement system

 

For the calibration of the transformer or sensor under test with a nominal current of ≤ 10A, TH0410 can be used directly as the standard device, with a broadband constant current source and a broadband sensor tester ( vector voltage analyzer), etc. to form a broadband transformer/sensor measurement system.

• Build a broadband transformer/sensor calibration system

For calibration of transformers or sensors with nominal currents greater than 10 A, TH0410 is used as a secondary signal I/V converter for standard and tested equipment, with broadband constant current source, Broadband sensor testers (vector voltage analyzers), etc. form broadband transformers/sensor measurement systems.

 

☆ Set up sensor bandwidth calibration system

TH0410 can be used with broadband standard voltmeters (such as TH20 0 0 vector voltage analyzer) to form a sensor bandwidth calibration system.

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.
