Smart energy meter with lcd electronic electricity single phase plc

DDS226L Single-phase Electronic Multi-function Energy

Meter General

DDS226L single phase electronic Kwh meter adopts large scale integrated circuit,with features of less peripheral miscellaneous, simple structure, high reliability, lowconsumption and long life. It can be used for single phase AC active electric energywith rate frequency of 50Hz.

Function and features

1.Measuring function: measure forward direction and reverse direction active powerand store the data to setup combination function. Measuring zero line *(selectable): live linezero line respectively sampling; measuring respectively;change-over automatically when power differs 10%.

2.Time function: with hardware time circuit of temperature compensation, it hascalendar and time, also can automatic switching bissextile; within -25℃ and+60℃, the time accuracy is ≤+1s/d; with the reference temperature of 23℃, timeaccuracy is ≤+0.5s/d.

3.Freezing function: the meter can fix time freezing, instant freezing, day freezing,etc.

4.Measure and detection: measure, record and display data of the meter, such asvoltage, current, power, power factor. Fiducial error less than ±1%.

5.Security protection: Programming switch box and password prevent theunauthorized person to operate the programme. Operate the meter only allowedto program it, time broadcasting and data reading not controlled by theprogramming switch.

6.Display methods: register, LCD, digital tube.

7.Communication methods: infrared interface and RS485 interface.

8.Power on/off function: the load switch is available and it is built-in.
