DDS1977 Type single-phase Electronic abstraction-of-Electricity prevention watt-hour meter
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.
