Application |
Model
DEM312TG single phase electronic front board
installed active energy meter is 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
single phase active energy meter stipulated
in international standard IEC 62053-21. It
can accurate and directly measure 50Hz or
60Hz active energy consumption from single
phase 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.

Functions and
features |
¡ñ
Front board three fixed
installation, up and down mounting holes
center distance is 130-147 mm, users can
choose any one by
themselves.
¡ñ Standard
configuration 5+1 digits display
(99999.1kWh) by step motor type impulse
register. May select 6+1 digits display
(Product Configuration
code is DC).
¡ñ Standard
configuration one port of pulse output
passive (polarity),
May select increase a
distant port of pulse output passive
(nonpolarity). And
contact with all kind of AMR system
conveniently,
Complying with standard IEC 62053-31 and DIN
43864.
¡ñ Two LED
instructions power supply state (green) and
signal of energy impulse (red).
¡ñ Automatic
detection the direction of the flow of load
current. And instructions by individual LED.
(Only yellow energy impulse
signal when working, that
is meaning the direction of the flow of load
current reverse).
¡ñ Single direction
single component measure single phase two
wire active energy consumption. It is
nothing with direction of the
flow of load current.
Complying with standard IEC 62053-21.
¡ñ Direct connect
operation, there are two types wiring you
may select. Standard configuration type 1A
wiring, may select type 1B
wiring (Product
Configuration code is AG).
¡ñ Standard
configuration short terminals cover, may
select extension terminals cover, in order
to protect to use safety. (Product
Configuration code is TH). |
