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:
