De vooruitbetaalde Slimme Meter van de Energie van de Enige Fase Elektro

------------------------------------Functions & Features--------------------------------
1.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.
 
2.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.
 
3.Temperature and Humidity functions
Energy meter has 2 temperature and humidity interfaces which can gather the appropriate temperature and humidity after accessing the temperature and humidity module.
 
4.Communication function
With RS232/RS485 communication port.
With ETH standard network communication
With wireless communication function, insert unicom SIM card which can use wireless network or SMS transmission data.
