Abstract

The utility model discloses a multifunctional digital-display electric power meter including a processor. An input terminal of the processor is connected with a power unit, an electrically meter metering IC, a switching value signal input terminal and a press key output module respectively. An output terminal of the processor is connected with a display screen composed of three-row four-bit LEDs, an output terminal of a 4-20 MA transmitter and a switching value signal output terminal respectively. The processor is also connected with a communication module and can measure electrical parameters such as current, voltage, power, power factors, frequency, electric energy and the like in a power grid. The three-row four-bit LEDs are adopted for displaying and a MODBUS-RTU communication protocol is adopted, so that convenience is made for programming setting and data reading. The multifunctional digital-display electric power meter is widely applied to different systems for power distribution, power metering, power acquisition and power transmission.
