summary
Multi functional power meters use advanced microprocessors and digital signal processing technology. Through direct AC sampling, they can measure electrical parameters such as current, voltage, active power, reactive power, power factor, frequency, active energy, and reactive energy. They can also be equipped with switch input and output, analog transmission output, power pulse output, and RS485 network communication functions. As an advanced intelligent and digital front-end acquisition component for power grids, this instrument is widely used in various control systems, industrial automation, intelligent buildings, intelligent distribution panels, and switch boxes. It has the characteristics of easy installation, simple wiring, easy maintenance, small engineering quantity, and programmable input parameters on site. Capable of networking different PLCs and industrial control computer communication software in the industry.
