Model
DEM341BM three phase four wire electronic multi-rate front board
installed active energy meter is a kind of three
phase four wire two
tariffs (tariff conversion is controlled by timer outside or similar
equipment) active energy meter, the
meter completely
accord with relevant technical requirements of class 1 three phase
active energy meter stipulated in
international
standard IEC 62053-21. It can accurately and directly measure 50Hz or
60Hz active energy consumption from
three phase four
wire AC electricity net, it is use for install in meter box indoor or
out door. This meter has seven digits LCD
monitors shows
various consumption data and information. And there are far infrared and
RS485 communication module
in it. It is use
for setting and reading the meter. Contact with all kind of AMR system
conveniently. It has following features:
Good reliability,
light weight, specious nice appearance, convenient installation, etc.

Function and features: |
|
-- Front
board three fixed holes installation, up and down mounting holes
center distance is
198-212 mm, users can choose any one by themselves.
--Have two tariffs, and port of set the tariff, input control
voltage 0-90 Vac, set up tariff F1,
input control voltage 150-400 Vac, set up tariff F2,
the tariff conversion is controlled by timer
outside or similar equipment.
--May
select cycle display (default) or push the button itemized display,
we can set the cycle
display, it can display 14 data
at most. Can select the data which displayed. The decimal
median
which displayed can choose set one or two.
--Use memory that is not loss easy, the data can be kept forever
after power cut off.
--There is a polarity port of
pulse output passive closed and a no polarity port of pulse
output
passive distant, the output rate
is 10 or 100 imp/kWh (can select),Complying with
standard IEC 62053-31 and DIN 43864.
--There
are far infrared and a port of RS485 communication data. It is use
for setting and
reading the meter. Set and operation
have password protection, communication protloc
complying with standard DL/T645-1997.
--Nine
LED instructions respectively power state, signal of power impulse,
the direction of
the trend of load current, the state
rates just now and the data communications state.
--Single
direction three components measure three phase four wire active
power
consumption.
It is nothing with direction of the
trend of load current. Complying with
standard IEC 62053-21.
--Standard configuration for direct connect and use, type 16B
connection, we can also
choose another type of connection,
and use CT (Product Configuration code is BO) and
PT & CT (Product Configuration code is BQ), type
48B connection
for operation.
--Standard
configuration short terminals cover, may select extended terminals
cover, in
order to protect to use electricity
safely. (Product Configuration code is BL). |
