Description

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****5—***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, etc relative assistant information • Display current total energy consumption when power off and also have inquiry function by button. • 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.
