Function and characteristic:

1.it has eight tariffs T1T2T3T4T5T6T7T8, every day you could set 48 period time most.

2.it using width temperature type double big screens display present totalT1T2 and present working tariffs consumption; programmable display present T3T8 consumptionmeter addresstimedatelast month sharing-time and total consumption each meters instantaneous parameter, at same time displays reactive energy parameter which is relevant to active energy; display-phase display alternately, alternately display time 1 second255secondsand alternate display could be management.

3.it has infrared and RS485 communication interface, could use the metering machine through infrared programming and metering; also has the PLC modular interface function.

4.its using non-volatile memory save data, could keeping a long period of time after power off; adopt hardware with temperature-compensation clock circuit, in the working temperature range and under the working condition, the accuracy of the clock is superior 0.5 second/day.

5.adopt saving data when power off, could keep the impulse quantity of each tariff effectively, up to reliable measuring; keep last 12 months total EC and every period-time electrical energy, could through communication read the relevant data.

6.It has the record of power off 30 times, no voltage record 30 times, meter installment (programming and open/cover case) event records, and also detect the working condition all the time, when the meters voltage phases have something wrong or lack phase, it will light LCD as warning mark.

7.Programmable set metering data and at the same time save all kinds of data of last month automatically.

8.Power limit
