Description

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 IEC***6 and all the technical requirements of GB/T*********2 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 *0 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.
