DDS2 кВтч метр

DDS2-L1 TYPE SINGLE-PHASE ELECTRONIC POWER METER The type DDS2-L1 single-phase meter is designed for measuring energy in household and commercial single-phase network services. It adopts the integrate circuit ADE7755 professionally used for measuring energy. The accuracy basically can't be affected by temperature,voltage and high harmonics.After a piece of meter sold out from the factory,it did not need any adjustment thus significantly delay the inspection cycle.The meter's performance conform to IEC1036,IEC62052-11,IEC62053-21 and GB/T17215-2002 Standard. It also has infrared and 485 communication functions and the communication stipulation support Multi Function Power Meter Communication Stipulation MAIN FEATURE: Accurately measuring of positive, negative cumulative energy consumption. Adopt LCD with wide temperature and wide visual angle. Register the energy of current month and total amount of last 12 months. Digits of the display pattern are six integers and one decimal. Display date, time, No. of the meter, etc relative assistant information. Anti-tamper function and can display the mark of negative power. Display current total energy consumption when power off and also have enquiry function by button Program the system with the function of preventing quick operation bring by fault of parts Infrared and 485 communication function, support metering by shorten digits meter number Average using lifetime can reach more than 10 years
