The  DDS5558 single phase electronic meters adopt exclusive use LSI, the device typifying few periphery component, simple structure , high  reliability, low power consumption, long life etc, is suitable for the single-phase AC active electric energy with rated frequency of 50Hz; the performance is in conformity with the technical requirements for single-phase electronic watt-hour meter stipulated in GB/T17215 321 -2008 Class I and 2 Static AC Active Watt-hour Meter standard

Function and Feature

1.Measure active electric energy, do not need calibrate for long-term operation

2.Long service life, accessiblel0 years

3.Sampling current at the same time between phase line and middle line, use the larger as valid  sampling, abstraction -of-electricity prevention one fire one ground thoroughly

4.Adopt exclusive use LSI and SMT surface fixing technique, having advance technology and simple structure

5.Adopt the latest oversea electric energy special integration circuit, greatly improved dynamic working range of Meter

6.Have good mistake linearity in the range of5%lb-lmax

7.Adopt high reliability and long life electronic component, so the Meter assume  feature of  high  reliability and long life

8.Low self power consumption, mighty overload
