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
