summary:

Multi functional power meter is a multifunctional power meter with programmable measurement, display, digital communication, and power pulse output functions, which can complete power measurement. Energy metering, data display, acquisition, and transmission are capable of high-precision measurement of commonly used electrical parameters in three-phase power grid systems, including three-phase voltage, current, active power, reactive power, apparent power, power factor, grid frequency, active energy, and reactive energy. They also come with communication interfaces and energy pulse output functions. Adopting the standard RS485 MODBUS-RTU communication protocol, LED/LCD on-site display and remote RS485 digital communication are achieved.
