| Abstract: | Considering the actual demand of power management and industrial automation,the electric parameter detection system based on PAC1921 high-side current/power sensor was designed. The measurement results are automatically configured to match the measuring range and the actual value, so that the design of the detection system has a wide measurement range and can ensure the measurement accuracy. The experimental prove the system can measure the value of 0-20 A current, 0-32 V voltage and 0-640 W power and the data acquisition is stable and it has high measurement accuracy. The system can provide a reference for the wide range of electrical parameters measurement and it has a certain reference value. |
