Description
ã€Overview】
Adopting advanced integrated circuit design and manufactured with
advanced SMT and re-flow soldering technology, single phase local
tariff control smart meter DDZY***2C-Z has the features of
accuracy, high overload, low power consumption and strong
capability of resisting disturbance. And the meter was equipped
with infrared palmtop, RS**5, power line carrier communication
connection, which can ensure the customer program, timing and
reading the meter by themselves.
ã€Function
overview】
