Application |
|
Model
DEM321DI 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, 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.

-- Front
board three fixed holes installation, up and down mounting holes
center distance
is198-212 mm, users can choose
any one by themselves.
--Standard
configuration 6 digits display (999999KWh) by step and motor type
impulse
register, may select 7 digits display
(Product Configuration code is DK)
--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). And contact with all kind
of AMR system conveniently,Complying with
standard
IEC 62053-31 and DIN 43864.
--Five
LED instructions respectively power state and signal of closed power
impulse and
distant power impulse.
--Automatic
Detect the direction of the trend of load current. And Instructions
on individual
LED.
--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 CI) and PT & CT (Product
Configuration
code is BI) 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 DF). |
