DDSF732-L1 TYPE SINGLE-PHASE ELECTRONIC MULTI RATE POWER METER

The DDSF732-L1 type 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.

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 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 10 years.

· 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.
