Display three-phase voltage ammeter LCD multifunction

Display three-phase voltage ammeter LCD multifunction   A multifunctional power meter is a device for measuring and monitoring various electrical parameters in a power system. It is designed to provide accurate and real-time data on power consumption, voltage, current, power factor, frequency and other electrical parameters. Electrical requirements: 1. Power consumption: Under reference voltage, reference temperature, and reference frequency, the active power and apparent power of the voltage line of the energy meter are less than 1W and 6VA; At the basic current, reference temperature, and reference frequency, the apparent power of the current line of the energy meter is less than 1VA 2. Voltage and voltage impact: The specified working range is 0.9Un to 1.1Un, the maximum working range is 0.7Un to 1.3Un, and a 380V voltage is applied to the voltage line for 1 hour without any damage. After the test, the meter should be able to work normally 3. Power interruption impact: Aft…
