DEM031BM
Single phase electric Multi-rate Din-Rail Active Energy Meter |
|
|
Application |
|
Model
DEM031BM single phase electronic multi-rate DIN rail active energy
meter is a kind of single phase two wire two
tariffs (tariff
conversion is controlled by timer outside or similar equipment) active
energy watt-hour meter. 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 accurately and directly measure 50Hz or
60Hz active energy consumption
from single phase
AC electricity net. 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, small volume, light weight,
specious nice
appearance, convenient installation, etc. This meter has already got the
patent certificate from Chinese
national
Intellectual Property Office at present. Patent certificate NO. ZL 2006
3 0106828.1, any other country patent
certificate are in
assessing. |

-- 35mm
standard DIN rail installation , complying with standard DIN
EN50022. Or front
board setting (mounting holescenter distance 63 mm),
users can choose any one by
themselves.
--Six
pole width (Modulus 12.5mm), complying with standard JB/T7121-1993.
--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,
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 lost easily, the data can be kept forever
after power cut off.
--A
port of pulse output passive (polarity), complying with standard IEC
62053-31.
--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 protecol
complying with standard DL/T645-1997.
--Six
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 measure single phase two wire active power consumption. It
is nothing
with direction of the trend of
load
current. Complying with standard IEC 62053-21.
--Standard
configuration type S connection (Inlet from bottom, outlet from top)
for direct
connect to use, we can also
choose
another type of connection, and use CT (Product
Configuration code is BO) and PT & CT (Product
Configuration
code
is BQ) for operation.
--Standard
configuration extended terminals cover, may select short terminals
cover, in
order to protect to use
electricity
safely. (Product Configuration code is BL). |
