DDSY5558 IC card prepaid/prepayment electricity energy meter
Product Brief introduction
The DDSY5558 type single-phase electronic watt-hour meter 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
Measure active electric energy,do not need calibrate for long-term
operation;
Long service life,accessiblel0 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 dimple structure;
Adopt the latest oversea electric energy special integration
circuit,greatly improved dynamic working range of Meter;
Have good mistake linearity in the range of5%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
