Application |
Model
DEM041AR three phase four wire electronic
multi-rate DIN rail 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
accurate and directly measure 50Hz or 60Hz
active energy consumption from three phase
four wire AC electricity net. This meter has
seven digits LCD displays 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
China State Intellectual Property Office at
present. Patent certificate NO. ZL 2006 3
0107349.1, any other country patent
certificate are in assessing.

arbitrary which can automatic read the meter
every month. May select single tariff
function in weekend. (Please specified when
ordering)
¡ñ
There are 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
blackout.
¡ñ
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.
Data 5+2 digits(99999.91kWh, Only when CT
ratio 5:5A) or 7 digits display. It is
choose by the CT ratio which is set.
¡ñ
There are a polarity port of pulse output
passive closed and a nonpolarity port of
pulse output passive distant, the output
rate is 10 kWh/ Pulse), 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. Set and operation
have password protection, communication
agreement complying with standard
DL/T645-1997.
¡ñ
Ten LED instructions respectively power
supply state, signal of energy impulse, the
direction of the flow of load current, the
tariff state just now and the data
communications state.
¡ñ
Single direction three components measure
three phase four wire active energy
consumption. It is nothing with direction of
the flow of load current. Complying with
standard IEC 62053-21.
¡ñ
Standard configuration short terminals
cover, may select extension terminals cover,
in order to protect to use safety. (Product
Configuration code is AS). |
