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*********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 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.
