Product Description

1. Summary

TH0780 is a high-precision power frequency voltage converter with built-in multi-position precision voltage transformers, which can convert large power frequency voltages into 1V output, and realize precise measurement of power frequency voltage or traceable calibration of voltage sources.
 

2. Feature

1. U₁ Nominal Input: 60 V ~ 480 V
2. U₂ Nominal Output: 1V
3. Working Frequency: 45 Hz ~ 65 Hz
4. Ratio Typical Uncertainty: 5 ppm
5. Select different ratios by touch on the LCD screen.
6. The voltage output can be turned off or on with one key.

 

3. Application

1. Power Frequency Voltage Precision Measurement
2. Power Frequency Voltage Standard Source Traceability

 

☆ Power Frequency Voltage Precision Measurement

1. Combined with a precision voltmeter (such as TH0190) to build a precision current measurement system.
2. Measure power frequency voltage or calibrate power frequency voltage source.

 

☆ Power Frequency Voltage Standard Source Traceability

1. The secondary voltage output by TH0780 is compared with the AC voltage reference through the zero voltage meter.
2. The ultra-high calibration uncertainty realizes the precise traceability of the power frequency voltage standard source.
