White Prepaid Electricity Meter , Large Current Compatible Home Electric Meter
Function and features
Main function
Measuring A, B, C threephase with active or reactive, etc, and could generate combination of active and reactive, and the maximum measurement is 24 road capacity.
lFor A, B,C threephase with active or reactive, the valid range of electric energy measurement is 0~99999999, the unit is kW·h or kvar·h;
lFor combination of active or reactive,the valid range of electric energy is 0~99999999, the unit is kW·h or kvar·h;
lHave the functions of power setting and a key to reset. Using the special debugging tools to set up or reset for A, B, C three-phase with active or reactive and combination of active or reactive power data of energy meter.
DC energy measurement
Measuring 6 load DC’s voltage, current, apparent power and parameters of electricity system, etc.
Clock, timer function
Clock has functions of calendar, timing, leap year automatic conversion.
Using relevant debugging tool or system platform to send timing order to do time calibration.
