Application |
|
Model
DEM321JF three phase four wire electronic front board installed
active energy meter is a kind of new style three
phase four wire
active energy meter, it adopt micro-electronics technique, and imported
large scale integrate circuit, use
advanced technique
of digital and SMT techniques, etc. 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
setting indoor or
out door, and this meter has seven digits LCD monitors shows the active
energy power consumption.
It has following
features: Good reliability, small volume, light weight , specious nice
appearance, convenient installation,etc.

Function and features: |
|
-- Front
board three fixed holes installation, up and down mounting holes
center distance
is198-212 mm, users can choose
any one by themselves.
--Seven
digits display LCD, standard configuration 6+1 digits display
(999999.1kWh,). May
select 5+2 digits display (Please
specified when ordering).
--Standard
configuration only a polarity port of pulse output passive, may
select add a no
polarity port of pulse output passive
distant ((Product Configuration code is DH). And
contact with all kind of AMR system conveniently,
Complying
with standard IEC 62053-31
and DIN 43864.
--Four
LED instructions respectively power state and signal of power
impulse.
--Automatic
Detect the direction of the trend of load current. And Instructions
on individual
LED.
--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 direct connect and use, type 16B connection, we can
also choose
another type of connection, and
use CT (Product Configuration code is HF) and PT & CT
(Product Configuration code is IF) for operation, it is
type 48B
connection.
--Standard configuration
extended terminals cover, may select short terminals cover, in
order to protect to use electricity
safely. (Product Configuration code is JC). |
