Product Description

TH0680 Multiplexing I/V Selection Units

1. Summary

TH0680 is a high-precision power frequency current converter with built-in multi-gear precision transformers and precision resistors, which can convert power frequency current into 1V voltage signal output, and realize precise measurement of power frequency current or traceable calibration of current source .

2. Feature

• I1 Nominal Input: 0.5 A ~ 100 A

• U2 Nominal Output:1V

• Working Frequency: 45 Hz ~ 65 Hz

• Typical Value of Ratio Measurement Uncertainty: 5 ppm

• LCD Touch Screen

• The voltage output can be turned off or on with one key.

3. Application

• Power Frequency Current Precision Measurement

• Power Frequency Current Standard Source Traceability

☆ Power Frequency Current Precision Measurement

• Combined with a precision voltmeter (such as TH0190) to build a precision current measurement system.

• Measure power frequency current or calibrate power frequency current standard source.

☆ Power Frequency Current Standard Source Traceability

• The secondary voltage output by TH0680 is compared with the AC voltage reference through the zero voltage meter.

• Ultra-high calibration uncertainty can be obtained, and precise traceability of power frequency current standard sources can be realized.
