Model
DEM341AM three phase four wire electronic multi-rate front board
installed active energy meter is a kind of three
phase four wire
three tariffs (time-sharing billing)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.

is a clock and Maintenance-free backup lithium batteries in it.
Battery capacity
detection and display all the time.
It can keep the electricity data for 12 months. The data
can be kept forever after power cut off.
--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.
--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.
--Ten
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 AO) and PT
& CT (Product Configuration code is AQ), 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 AL). |
