General introduction

Model DDSF881 electronic single-phase multi-tariff watt-hour meter is used to measure AC50Hz 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 ofthe data during usage. Its special techniques can ensure the data been memorizedautomatically 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 toensure the high accuracy of the time switch. And its standard infrared communicationport or 485 communication (this function can be select) finishes the functionsetting, clock setting, tariff setting and period program. This product is suitable for the ambient temperature of -45 to +70 Celsius degreesand relative humidity less than 85%.Its performance complies with the relative technical requirements for class 1 single-phasewatt-hour meter in GB/T17215-2002 (IEC61036-2000), and its data communicationrules obey the requirements of DL/T645-1997.
