  • More high-precision energy metering chip was adopted to realize the function of the multiplex three-phase watt-hour meter.

    Positive/reverse every road watt-hour meter with active and combination active data.

    Every road watt-hour meter can measure current voltage frequency power factor have/reactive power apparent power.

    Recording and alarming under voltage over voltage over pressure phase failure and other events.

    On the automatic meter reading day a month settlement to power meter automatically.

    Able to freeze timing the top of the hour day. The energy meter can be frozen with data such as electricity 30 time freezes 254 total freezing 62 days frozen.

    With RS485 interface the pulse acquisition public 2G / 3G / 4G communication interface.

    RS485 interface with meter reading function able to copy DL/T 645 agreement Modbus protocol smart meter;

    Terminal support oneself road 4 meters and external 28 biggest smart meter data acquisition.

    Terminal can store up to 32 table only once every 30 minutes meter meter reading data of 15 days.

    Terminal has a table showing the electricity pulse acquisition function to monitor power in total table data.

    Clock with calendar timing leap year automatic conversion function.

    Can use relevant debugging tools or the system platform to send school time calibration command.

    Electric meter with functions of monitoring of all kinds of abnormal operation and with abnormal information display including abnormal watt-hour meter fault class tooltips and abnormal event classes and so on and so forth.

    Support private network access terminal private network APN can be configured by setting the software.

    Control output: instrument shell output electrical pulse or level switch signal control the external alarm device or load switch. (optional)
