Specification :

DDS2-L1 TYPE SINGLE-PHASE ELECTRONIC POWER METER
The type DDS2-L1 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. It also have the infrared and 485 communication functions, the communication stipulation support
DL/ T645— 1997
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 12 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 485 communication function, support metering by shorten digits meter number.
• Average using lifetime can reach more than 10 years.
