 Electronic Single-phase Multi-rate Smart Meter Model DDSFI846 |
|
 Functions and characteristics:
1. Able to accurately measure active power electric energy, reverse electric energy accumulated as forward active power electric energy. Good linearity in measurement
of electric energy and a wide dynamic working scope;
2. Peak, flat and valley rates measured separately, time-periods shifted by built-in clock, automatic shift between calender, timing and leap year;
3. After power outage, all stored data can be kept for more than 10 years;
4. Provided with standard infrared communication interface, able to read the current total electric quantity from handheld terminal, current peak electric quantity,
current valley electric quantity, total electric quantity of previous month, peak electric quantity of previous month, average electric quantity of last month, and valley
electric quantity of last month;
5. Possible to set up and read parameters of electric quantity through RS485 communication interface;
6. LCD used to display date, time, meter address, meter constant, current total electric quantity, current peak electric quantity, current flat electric quantity and current
valley electric quantity.(原中文有7条)
