Application |
Model
DEM312BS single phase electronic front board
installed active energy meter is adopt
micro-electronics technique, and imported
large scale integrate circuit, use advanced
technique of digital and SMT techniques,
etc. The meter completely accord with
relevant technical requirements of class 1
single phase active energy meter stipulated
in international standard IEC 62053-21. It
can accurate and directly measure 50Hz or
60Hz active energy consumption from single
phase AC electricity net, it is use for
setting indoor or out door, and this meter
has seven digits LCD displays shows the
active energy consumption. And there are far
infrared and RS485 communication module in
it. Contact with all kind of AMR system
conveniently. It has following features:
good reliability, small volume, light
weight, specious nice appearance, convenient
installation, etc.

Functions and
features |
¡ñ
Front board three fixed
installation, up and down mounting holes
center distance is 130-147 mm, users can
choose any one by
themselves.
¡ñ May select 6+1
digits display (999999.1kWh) or 5+2 digits
display, it can be arbitrary set by users
from far infrared or port of
RS485 data communication.
¡ñ Standard
configuration one port of pulse output
passive (polarity),
May select increase a
distant port of pulse output passive
(nonpolarity). And
contact with all kind of AMR system
conveniently,
Complying with standard IEC 62053-31 and DIN
43864.
¡ñ There are a port
of far infrared data communication and a
port of RS485 data communication. Standard
configuration
communication agreement complying with
standard DL/T645-1997, can also choose any
other communication agreement.
¡ñ Three LED
instructions power supply state, signal of
energy impulse and communication state.
¡ñ Automatic
detection the direction of the flow of load
current. And instructions by individual LED.
(Only yellow energy pulse signal
when working, that is
meaning the direction of the flow of load
current reverse).
¡ñ Single direction
single component measure single phase two
wire active energy consumption. It is
nothing with direction of the
flow of load current.
Complying with standard IEC 62053-21.
¡ñ Direct connect
operation, there are two types wiring you
may select. Standard configuration type 1A
wiring, may select type 1B
wiring (Product
Configuration code is GF).
¡ñ Standard
configuration extension terminals cover, in
order to protect to use safety, may select
short terminals cover. (Product
Configuration code is
BR). |
