Two Phase Three Wire
Electronic Din-Rail Active Static Electricity Meters 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 accurately and directly
measure 50Hz or
60Hz active energy consumption from two phase three wire AC electricity
net. This meter has seven
digits LCD monitors
shows the active energy power consumption. And there are far infrared
and RS485 communication
module in it.
Contact with all kind of AMR system conveniently 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.

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.
-Two
Phase Three Wire Electronic Din-Rail Active Static Electricity
Meters-Ten pole width (Modulus
12.5mm), complying with standard JB/T7121-1993.
-Two
Phase Three Wire Electronic Din-Rail Active Static Electricity
Meters-May
select 6+1 digits display (999999.1kWh) or 5+2 digits display, it
can be arbitrary set by
users from far infrared or
port of RS485 data communication.
-Two Phase Three
Wire Electronic Din-Rail Active Static Electricity 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 100imp/ KWh, can select). Complying with
standard IEC 62053-31 and DIN 43864.
-Two Phase Three
Wire Electronic Din-Rail Active Static Electricity Meters-There
are a port of far infrared data communication and a port of RS485
data
communication. Standard configuration communication
protelot complying with standard
DL/T645-1997,
can also choose any other communication agreement.
-Two
Phase Three Wire Electronic Din-Rail Active Static Electricity
Meters-Five
LED instructions respectively power state (line voltage L1 &
L3), signal of closed
power impulse and distant power impulse and data
communication state.
-Two
Phase Three Wire Electronic Din-Rail Active Static Electricity
Meters-Automatic
Detect the direction of the trend of load current. And Instructions
on individual
LED.
-Two Phase Three
Wire Electronic Din-Rail Active Static Electricity 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.
-Two Phase Three
Wire Electronic Din-Rail Active Static Electricity 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 CT (Product
Configuration code is FA) and PT & CT (Product
Configuration code
is EA) for operation.
-Two Phase Three
Wire Electronic Din-Rail Active Static Electricity Meters-Standard
configuration extended terminals cover, may select short terminals
cover, in
order to protect to use electricity
safely. (Product Configuration code is GD). |
