General introduction
Model DDSF881 electrical single-phase multi-tariff watt-hour meter is used to measure AC
50Hz active energy, with features of long life, high accuracy, good overload,
low power consumption and small size.
The meter adopts fault-tolerant technique to ensure calibration and correction of
the data during usage. Its special techniques can ensure the data been memorized
automatically scroll the accumulative energy, accumulative energy of each tariff,
present date and time, and signal of present tariff.
The power of real time clock chip is supplied by large capacity lithium battery to
ensure the high accuracy of the time switch. And its standard infrared communication
port or 485 communication (this function can be select) finishes the function
setting, clock setting, tariff setting and period program.
This product is suitable for the ambient temperature of -45 to +70 Celsius degrees
and relative humidity less than 85%.
Its performance complies with the relative technical requirements for class 1 single-phase
watt-hour meter in GB/T17215-2002 (IEC61036-2000), and its data communication
rules obey the requirements of DL/T645-1997.
