Multi-rate energy meter(watt meter,electric counte

Product Brief Introduction Multi-rate energy meter(watt meter,electric counter)can metering active forward and reverse direction accurately, own the function of recording the max demand ,measure and process the voltage, current ,power etc parameter all the time. Own the function of time-sharing control, reading automatic, data storage of electric quantity and demand quantity ,the record of current operate state and event record etc.which is a ideal intelligent instrument of realizing time-sharing metering and checking working. This kwh adopt large scream LCD to display with the port of remote infrared, RS485 etc. Function and&nbsp; features 1Each of four periods has different rates(point period, peak period, smooth period and trough period). Every period of time can be programmed into 12 periods of time and the minimum time interval is five minutes 2. All the consumption date can be reserved for 12 months 3. The meter adopts the advanced energy measuring chips,&nbsp; high capability CPU and RTC clock chips 4. Recording the active electric quantity and the electric quantity under every rate, and reserved it 5. High accuracy, sensitivity and reliability, wide overload endurance, low power consumption and light in weight 6. Auto accumulate and recording the working time of the battery 7. Display the present time, rate, total electric power and every rate electric power 8. Communicate Agreement accord with DL/T645-1997 9. It has pulse output communication, pulse width:80ms±20ms 10. It adopts the password and program switch protection, recording the latest program time and degree 11. It can setup the meter number, bureau numbertime-periodratedatetime, meter reading time, password and the initial electric power 12. Can move through some form cover wheel show button look over the electric consumption parameter that users select 13. Own the function of measuring the max demand quantity.
