Model
DEM481RC three phase four wire electronic multi-rate prepayment
front board installed active energy meter is a
kind of three phase
four wire active energy meter which purchase electricity by IC card,
electric energy measuring, load
control and using
electricity management. 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 three phase four wire AC electricity
net, it is use for setting
indoor or out door
meter box. This meter has LED monitors shows power. And there is far
infrared communication module
in it, can read the
meter and set the system parameters conveniently. It has following
features: Good reliability, light
weight, specious
nice appearance, convenient installation, etc.

Function and features: |
|
-- Standard
configuration one meter with one card, can repeat input money from
PC machine
which with IC programmer.
--There
a clock which is implement ladder rate, and there is far infrared
communication
module in it, use for checking the
clock, reading the meter and setting the system
parameters.
--It
has IC card with code and data against false, standard configuration
use storage IC
card, may select logic encryption
card (Product Configuration code is RG) or non-contact
RF card. (Product Configuration code is RK)
--Standard
configuration payment by kWh, may select payment by money. (Please
specified
when ordering).
--Standard
configuration of the prepayment management system use of single
version, may
select network version. (Please
specified when ordering).
--It
has load control and function of automatic fault detection and
instructions, standard
configuration without function of
open terminals cover and detection, may select open
terminals cover and power cut. (Please specified when
ordering).
--6
LED digits display, 5+1 digits display (99999.1kWh), may select 7
LCD digits display.
(Product Configuration code is
SC).
--A
port of pulse output passive closed (polarity), complying with
standard IEC 62053-31 and
standard DIN 43864.
--Five
LED instructions power state, signal of power impulse and direction
of the trend of
load current.
--Automatic
detect the direction of the trend of load current. When the yellow
LED display,
that is meaning the current reverse.
--Single
direction three component measure three phase four wire active
energy
consumption. It is nothing with direction
of
the trend of load current. Complying with
standard IEC 62053-21.
--Direct
connect and use, type 16B wiring, may select three phase three wire,
direct connect
operation, type 13B connection
(Product Configuration code is RD).
--Front
board three fixed holes installation, standard configuration short
terminals cover,
may select extended terminals cover,
in order to protect to use electricity safely. (Product
Configuration code is RA). |
