Model
DEM031CM 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 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
accurate and directly measure 50Hz or 60Hz
active energy consumption from single phase
AC electricity net. This meter has seven
digits LCD displays shows various
consumption data and information. 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 China State Intellectual
Property Office at present. Patent
certificate NO. ZL 2006 3 0106828.1, any
other country patent certificate are in
assessing..

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.
¡ñ
Standard configuration type of cycle
display, cycle display is 5 seconds. It can
display 6 data at most. Can select the data
which displayed. (Please specified when
ordering). The decimal median which
displayed can choose set one or two.
(Default two decimal, please specified when
ordering)
¡ñ
Use memory that is not loss easy, the data
can be kept forever after blackout.
¡ñ
Standard configuration pulse output passive
(polarity), May select distant impulse
output passive (nonpolarity). And contact
with
all kind of AMR system
conveniently, Complying with standard IEC
62053-31 and DIN 43864.
¡ñ
There are far infrared and a port of RS485
communication data. It is use for setting
and reading the meter, communication
agreement complying with standard
DL/T645-1997.
¡ñ
Five LED instructions respectively power
supply state, signal of energy impulse, the
direction of the flow of load current and
the
state rates just now.
¡ñ
Single direction measurement 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
Standard configuration type S wiring (Inlet
from bottom, outlet from top) for direct
connect operation, we can also choose
another type of wiring, and use CT (Product
Configuration code is CO) and PT & CT
(Product Configuration code is CQ) for
operation.
¡ñ
Standard configuration extension terminals
cover, in order to protect to use safety,
may select short terminals cover. (Product
Configuration code is CL). |
