DEM421JB
Three phase Three wire electronic Din-Rail Active and Integration Energy Meter |
|
|
Application |
|
Model
DEM421JB three phase three wire electronic DIN rail active and
reactive integration energy meter 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 and class 2
three phase
reactive energy meter stipulated in international standard IEC 62053-23.
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 type impulse register. This meter has seven digits LCD monitors
shows active power. 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.

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.
--Ten pole width (Modulus
12.5mm), complying with standard JB/T7121-1993.
--7
digits LCD display, 6+1 digits(999999. 1kWh) may select 5+2 digits
display. (Please
specified when ordering) There
is a maintenance-free lithium battery in it, use for showing
blackout reading.
--Standard
configuration one port of active pulse output passive and one port
of reactive
pulse output passive (polarity)
The output rate are 0.01, 0.1, 1, 10kWh or kvarh/Pulse.
Users can choose any one by themselves. May
select
one port of active pulse output
passive
and one port of reactive pulse output passive (no polarity). And
contact with all
kind of AMR system conveniently complying with standard
IEC 62053-31 and DIN 43864.
(Please specified when ordering)
--Four
LED instructions power state (line voltage L12 & L32) and signal
of active power
impulse and reactive power impulse.
--Automatic detect the direction of the trend of load current. And
instructions by one LED.
--Single
direction two components measure three phase three wire active
Power
consumption. It is nothing with direction
of
the trend of load current. Complying with
standard IEC 62053-21and IEC 62053-23.
--Standard
configuration type S connection (Inlet from top, outlet from
bottom), directly
connect to use, may select use CT
(Product Configuration code is IB) and PT&CT
(Product Configuration code is HB) for operation.
--Standard
configuration extended terminals cover, may select short terminals
cover, in
order to protect to use electricity
safely. (Product Configuration code is JE). |
