Application |
Model
DEM021DD two phase three wire electronic DIN
rail active energy meter is a kind of new
style two 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 accurate and directly
measure 50Hz or 60Hz active energy
consumption from two phase three wire AC
electricity net. It can display total energy
consumption by step motor impulse register.
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.

Functions and
features |
¡ñ
35mm standard DIN rail installation,
complying with standard DIN EN50022. Or
front board installed (mounting holes center
distance 63 mm), users can choose any one by
themselves.
¡ñ
Ten pole width (Modulus 12.5mm), complying
with standard JB/T7121-1993.
¡ñ
Standard configuration 6 digits display
(999999kWh) by step motor impulse register.
May select 7 digits display by impulse
register (Product Configuration code is BJ).
¡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 or 100 imp/kWh (can select). And
contact with all kind of AMR system
conveniently, Complying with standard IEC
62053-31 and DIN 43864.
¡ñ
Four LED instructions respectively power
supply state (phase voltage L1 & L3) and
signal of closed energy impulse and distant
energy impulse.
¡ñ
Automatic detection the direction of the
flow of load current. And instructions
(signal of closed energy impulse is green
when working, that is meaning the direction
of the flow of load current reverse).
¡ñ
Single direction two components measure two
phase three wire active energy consumption.
It is nothing with direction of the flow of
load current. Complying with standard IEC
62053-21.
¡ñ
Standard configuration type S wiring (Inlet
from bottom, outlet from top) for direct
connect operation, we can also choose
another type of wiring, and use 5+1 digits
display by impulse register, CT (Product
Configuration code is CD) and PT & CT
(Product Configuration code is BD) for
operation.
¡ñ
Standard configuration short terminals
cover, may select extension terminals cover,
in order to protect to use safety. (Product
Configuration code is DG). |
