    The design of this product refers to the standard design of intelligent electric energy meters, and adopts the SOC chip that is mass-produced and connected to the network in the national electric energy meter market, which meets the specification requirements of intelligent electric meters. The metering module is based on a high-performance low-power professional metering Soc chip. In the current 5000:1 dynamic range, the active metering error is less than 0.1%, and in the current 1000:1 dynamic range, the voltage/current effective value metering error is less than 0.5%, providing high-precision metering for the metering module.


software functions

    1. Support real-time recording of accumulated electric energy

    2. Support real-time data acquisition of voltage/current/active, reactive, apparent power/frequency/power factors.

    3. Support active reporting of power and accumulated power data every 5 minutes and hour (optional)

    4. Support active reporting of overvoltage, undervoltage and overload abnormal states

    5. Support UART communication protocol for convenient communication

    The metering module measures the real-time current at the load end by collecting the L live wire current through the manganese copper shunt, and measures the real-time voltage when the load works through the voltage between the resistance partial voltage Network acquisition L and the N wire. The metering module needs external 5V/3.3V power supply. The real-time power consumption information collected by the metering module can be read by an external system in real time through UART. The metering module also has 2 IO ports for other applications.
