Cnaob Three Phase Voltage Current Combined Meter

It is used to measure and display three phase voltage, three phase current in power system.

3.1 Measuring range(can overload 1.2 times continuously)
      3.1.1 Voltage
                Direct measurement: AC  10~600V                
      3.1.2 Current
               Direct measurement:AC  1A or 5A
               External current transformer:AC  */1A or */5A
3.2 Accuracy:class 0.5 
3.3 Sampling rate:1.5 times/s( can custom make as 3 times/s)
3.4 Input circuit power consumption: <0.5VA/phase
3.5 Display resolution:voltage max. 0.1V, current max.0.001A 
3.6 Auxiliary power supply: 220V         50/60Hz, <3VA 
3.7  Working environment:places which is free of gas corruption with temperature -10~50ºC,humidity              ≤85%RH 







1. Using the 32-bit single chip microprocessor and the 12 bit ADC over sampling and frequency automatic tracking technology, it has the advantages of quick sampling speed and high measurement accuracy.
2. Calibration by the software, using zero offset correction technology, the full range of linearity can reach 0.1%.
3. Based on the summary of more than ten years of technical service and quality feedback, the design and quality of the new instrument is stable and reliable. It provides the detailed menu parameter settings, simple operation and strong versatility. Many functions are the first design in China. "Fool" and "professional" to meet the customers with different needs.
4. Full usage of imported electronic components, integrated circuits, SMT chip manufacturing process.
 5. Adopt the isolated transformers, 3.3V linear voltage regulator power supply, it can save energy when it compare with the 5V system.
6. Full product type, optional specification, different size, LED/ LCD display screen optional, and with high quality and low price, high cost performance.
7. with independent intellectual property rights, in the shortest possible time for customers to tailor the required product features.
