|
|
Application |
|
Model
DEM321CT three phase three wire electronic front board installed
active energy meter is a kind of new style three
phase three 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 three wire AC
electricity net, it is use for
setting indoor or
out door, it can display total energy consumption by step and motor type
impulse register. 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.
--6
digits display (999999KWh) by step and motor type impulse register.
--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
convenient,Complying with
standard IEC 62053-31
and DIN 43864.
--Three
LED instructions respectively power state and signal of power
impulse.
--Standard
configuration don’t detection direction of the trend of load
current. May select
automatic Detecting the direction
of the trend of load current. And Instructions on individual
LED. (Please specified when ordering)
--Single
direction two components measure three phase three 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 5+1 digits display by impulse counter, CT (Product
Configuration code is CV) and PT & CT (Product
Configuration code is CX) 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 EH). |
