Description

DDS*-L1 TYPE SINGLE-PHASE ELECTRONIC POWER METER The type DDS*-L1 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. It also have the infrared and **5 communication functions, the communication stipulation support DL/T*******7 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 *2 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 **5 communication function, support metering by shorten digits meter number. •Average using lifetime can reach more than *0 years.
