Application |
Model
DEM231DH three phase three wire electronic
DIN rail reactive energy meter is a kind of
new style three phase three wire reactive
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 2 three phase reactive
energy meter stipulated in international
standard IEC 62053-21. It can accurate and
directly measure 50Hz or 60Hz active energy
consumption from three phase three wire AC
electricity net. It can display total energy
consumption by step motor type 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 type impulse
register. May select 7 digits display by
impulse counter (Product Configuration code
is CK).
¡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/kvarh, 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 (line voltage L12 & L32) 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
three phase three wire reactive energy
consumption. It is nothing with direction of
the flow of load current. Complying with
standard IEC 62053-23.
¡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 CH) and PT & CT
(Product Configuration code is BH) for
operation.
¡ñ
Standard configuration extension terminals
cover, in order to protect to use safety,
may select short terminals cover. (Product
Configuration code is DE). |
