Three-phase(LCD) Watt-hour Energy Meter

Detailed Product Description

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  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,  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.
