DDSF***-L1 TYPE SINGLE-PHASE ELECTRONIC MULTI RATE POWER METER

The DDSF***-L1 type single-phase meter is designed for measuring energy in household and commercial single-phase network services. It adopts the integrate circuit ADE***5 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 IEC***6,IEC*******1,IEC*******1 and GB/T*********2 Standard

MAIN FEATURE:
• Accurately measuring of positive, negative cumulative energy consumption.
• Set up one to four rates and eight using periods with user's requirement.
• Deposit current and last twelve months data of energy. 
• Adopt LCD with wide temperature and wide visual angle.
• Digits of the display pattern are six integers and one decimal.
• Display date,time,No. of the meter and etc relative assistant information.
• Display current total energy consumption when power off and also have enquiry function by
• Hardware clock's CMOS chip has the function of temperature compensation function.
• Adopts long lifetime pole type lithium battery whose using lifetime is more than *0 years
• Program the system with the function of preventing quick operation bring by fault of parts
• Infrared and **5 communication function, support metering by shorten digits meter number
• Average using lifetime can reach more than *0 years.
