Model
DEM331CO single phase electronic multi-rate front board installed
active energy meter is a kind of single phase
two wire three
tariffs (tariff conversion is controlled by timer outside or similar
equipment)active energy meter, the meter
completely accord
with relevant technical requirement 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 showing
various consumption data and
information. It has
following features: good reliability, light weight, specious nice
appearance, convenient installation,etc.

Function and features: |
|
-- Front
board three fixed holes installation, the cover is made of PC
material which is
transparent and anti-UV molded overall,
the base of the meter and the terminal block are
made of quality bakelite material which is
moisture-resistant, fire-retardant,
high
temperature molded overall. It has following features:
good weatherability, high rigid, good
insulation
performance, etc.
--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.
--Standard
configuration cycle display (default) every 5 second, it can display
6 data at most.
Can select the data which displayed.
The decimal median which displayed can choose
set one or two. (Default two decimal, please specified
when
ordering)
--Use
memory that is not loss easy, 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,communication protelot complying with
standard DL/T645-1997.
--Five
LCD instructions respectively power state, signal of power impulse,
the direction of
the trend of load current, the state
rates just now.
--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.
--Direct
connect and use, there are two types you may select. Standard
configuration type 1B
connection, may select type
1A connection (Product Configuration code is CM).
--Standard
configuration extended terminals cover, may select short terminals
cover, in
order to protect to use electricity
safely. (Product Configuration code is CN). |
