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.   The main features of the comprehensive multi-function power meter include:   1. Power measurement: accurately measure the active power, reactive power and apparent power of the power system. This allows users to monitor their energy consumption and identify areas where energy efficiency needs to be improved.   2. Voltage and current measurement: Measure the voltage and current levels in the power system. This information is essential to ensure the safe operation of electrical equipment and to identify any anomalies or faults.   3. Power factor measurement: The power factor is measured to reflect the power utilization rate of the sys…
