PRODUCT BRIEF INTRODUCTION
 
The DDS1977 type single-phase electronic watt-hour meter adopt exclusive use LSI , the device typifying few periphery component , simple structure , high reliability , Iow power consumption , long life etc , is suitable for the single-phase A.C active electric energy with rated frequency of 50Hz ; the perforrnance is in conformity with the technical requlrements for single-phase electronic watt - hour meter stipuIated in GB/T17215.321-2008 Class 1 and 2 Ststic A.C Active watt -hour Meter Standard.
 
FUNCTION AND FEATURES
Measure active electric energy , do not need calibrate for Iong-term operation ;
Long service life , accessible 10 years ;
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 ;
Adopt exclusive use LSI and SMT surface fixing technique , having advance technology and simple structure ;
Adopt the latest oversea electric energy special integration circuit , greatly improved dynamic working range of Meter ;
Have good mistake linearity in the range of 5% lb~lmax ;
Adopt high reliability and long life electronic component , so the Meter assume feature of high reliability and long life ;
Low self power consumption , mighty overload.
