DDSF726 Single-phase Electronic Multi-rate Energy Meter
General
The DDSF726 type electronic single-phase multi-rate watt-hour meter is composed by theelectronic single-phase watt-hour meter part and multi-rate part, LCD display,infrared orRS485 communication. It has high measuring accuracy, well stability, well over-load abilityand high reliability. It can measure the time-sharing single phase.
Function and features
1.Each of four periods has different rates (point period, peak period, smooth period andtrough period). Every period of time can be programmed into 12 periods of time andthe minimum time interval is one minutes;
2.All the consumption date can be reserved for 12 months;
3.It can auto identify the directional, will be auto save and accumulate to the forwarddirection power counter. It can automatically save the reverse direction power, startingtime and the total time;
4.It has the function of reverse directional pulse test and indication;
5.It has the isolated Rs485 communication, and design for prevent from the lightning strike;
6.Data-copying adopts the password and program switch protection, recording the latestprogram time and degree;
7.It adopts the hardware clock circuit, the lowest current consumption, the battery isonetime and environmental protection lithium battery;
8.It can setup the meter number, bureau number, time-period, rate, date, time, meterreading time, password and the initial electric power;
9.It can indicate the short voltage of the meter, the clock state, the directional electricmeter, the communication state, time adjusting and the present time-period, and readvia RS485 or handheld computer.
10.Reading the data automatically at power off
