TH0780 Multiplexing V/V Selection Units

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

• U1 Nominal Input: 60 V ~ 480 V

• U2 Nominal Output: 1V

• Working Frequency: 45 Hz ~ 65 Hz

• Ratio Typical Uncertainty: 5 ppm

• Select different ratios by touch on the LCD screen.

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

3. Application

• Power Frequency Voltage Precision Measurement

• Power Frequency Voltage Standard Source Traceability

☆ Power Frequency Voltage Precision Measurement

TH0780 Multiplexing VV Selection Units Measure power frequency voltage

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

• Measure power frequency voltage or calibrate power frequency voltage source.

☆ Power Frequency Voltage Standard Source Traceability

TH0780 Multiplexing VV Selection Units Precise Calibration of Power Frequency Voltage Standard Source

• The secondary voltage output by TH0780 is compared with the AC voltage reference through the zero voltage meter.

• The ultra-high calibration uncertainty realizes the precise traceability of the power frequency voltage standard source.
