Three Phase Three Wire
Electronic Din-Rail Active Static Kilowatt Hour Meters 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 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. This meter has
already got the patent certificate
from Chinese
national Intellectual Property Office at present. Patent certificate NO.
ZL 2006 3 0107349.1, any other
country patent
certificate are in assessing.

-Three
Phase Three Wire Electronic Din-Rail Active Static Kilowatt Hour
Meters- 35mm
standard DIN rail installation, complying with standard DIN EN50022.
Or front
board setting (mounting holes center
distance 63 mm), users can choose any one by
themselves.
-Three
Phase Three Wire Electronic Din-Rail Active Static Kilowatt Hour
Meters-Ten
pole width (Modulus 12.5mm), complying with standard JB/T7121-1993.
-Three
Phase Three Wire Electronic Din-Rail Active Static Kilowatt Hour
Meters-Standard
configuration 6 digits display (999999kWh) by step and motor type
impulse
counter. May select 7 digits display
by impulse counter (Product Configuration code is CJ).
-Three
Phase Three Wire Electronic Din-Rail Active Static Kilowatt Hour
Meters-There
are 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
-Three
Phase Three Wire Electronic Din-Rail Active Static Kilowatt Hour
Meters-Four
LED instructions respectively power state (line voltage L12 &
L32) and signal of
closed power impulse and distant power
impulse.
-Three
Phase Three Wire Electronic Din-Rail Active Static Kilowatt Hour
Meters-Automatic
Detect the direction of the trend of load current. And instructions
(signal of
closed power impulse is green when
working, that is meaning the load current reverse).
-Three
Phase Three Wire Electronic Din-Rail Active Static Kilowatt Hour
Meters-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.
-Three
Phase Three Wire Electronic Din-Rail Active Static Kilowatt Hour
Meters-Standard
configuration type S connection (Inlet from bottom, outlet from top)
for direct
connect to use, we can also choose
another type of connection, and use 5+1 digits
display by impulse counter, CT (Product Configuration
code is
CE) and PT & CT (Product
Configuration code is BE) for operation.
-Three
Phase Three Wire Electronic Din-Rail Active Static Kilowatt Hour
Meters-Standard
configuration extended terminals cover, may select short terminals
cover, in
order to protect to use electricity
safely. (Product Configuration code is DH). |
