 DDSIF566-L02

Single phase multi-rate PLC watt-hour meter
   
    DDSIF566 Single phase multi-rate PLC watt-hour meter is kind of new developed intelligent meter, which conforms to relative IEC standard, it has been tested through long term running at rigorous working site, It adopts large scale integration circuit as key component with advanced processing and simple structure to realize high reliability, tamper proof, enduring onerous load, high accuracy, error stability, low power consumption and strong communication ability
   
The meter is based on power line carrier and communication technique. It uses LV power line as its communication channel. Its core technique is software technique and power frequency modularized technique. Energy meter data can be transmitted to the remote centralized meter reading system of upper level in the mode of power line carrier style by using the mode identification and fuzzy processing technique.
    LCD display data, multiple functions, high-reliability and lower cost make the meters enable to measure 50Hz or 60Hz single phase active energy with three tariffs. It is an elaborate project that answers many purposes by adopting advanced vector arithmetic. It is a ideal scheme for domestic and commercial customer energy measuring with infrared communication interface and power line carrier for programming and meter reading.
    DDSIF566 series Single Phase electronic watt-hour meter conforms to the standards as follow: GB/T 17215-2002 (IEC61036-2000)
