DDS2-J2 SINGLE-PHASE ELECTRONIC WATT-HOUR METER
DDS2 SINGLE-PHASE ELECTRONIC WATT-HOUR METER
The type DDS2 used advanced ultra-low-power solid-state integrated circuits and SMT technology. The precision can not be affected by frequency, 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. All of its properties are in line with IEC1036 and all the technical requirements of GB/T17215-2002 standard 1.0 -- Single Phase.

MAIN FEATURE:
• Accurately measuring of positive, negative cumulative energy consumption
Adopts stepper motor counter displaying the total power
• Digits of the counter display are five integers and one decimal.
• Average using lifetime can reach more than 10 years
• Multi type anti-tamper function
•Counter motor is designed with multi lays screen shield which can prevent tamper energy by strong magnetism.
• There are optical ports set on the terminal block and remarked (+), (-), which will facilitate error testing.
