M type 0.5S-level three-phase cost-controlled intelligent electric
energy meter (module-remote-switch external)
Overview of M type 0.5S-level three-phase cost-controlled
intelligent electric energy meter
DTZY88-M type 0.5S-level three-phase cost-controlled intelligent
energy meter (module-remote-switch external) is a new generation of
high-precision intelligent three-phase energy meter, with active
and reactive energy time-sharing measurement, data processing, and
event recording , Load recording, automatic control, information
interaction and other functions, using large-screen LCD display to
facilitate reading of data, and provide infrared and remote
communication interfaces to facilitate remote computer management
in power departments. On this basis, functions such as AC magnetic
field anti-submarine, power supply abnormality monitoring,
anti-magnetic field and constant magnetic field monitoring are
added, which greatly enhances the anti-theft performance and
operational reliability; the communication module interface can
support the current domestic commonly used micro-power wireless,
The interchange of modules such as the wireless public network has
strong networking flexibility. This smart meter adopts a variety of
software and hardware anti-interference measures and redundant
design. It is manufactured by large-scale integrated circuit and
SMT technology. The key components are selected from
internationally renowned brands of long-life components, which
makes this energy meter highly reliable and more reliable. Long
operating life.
