Application |
Model
DEM312TL single phase three wire electronic
front board installed active energy meter is
a kind of new style single phase three wire
active energy meter, and 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
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 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.

Functions and
features |
¡ñ
Front board three fixed
installation, up and down mounting holes
center distance 130-147 mm, users can choose
any one by
themselves.
¡ñ 5+1 digits
display (99999.1kWh) by step motor type
impulse register.
¡ñ Standard
configuration one port of pulse output
passive (polarity),
May select increase a
distant port of pulse output passive ( no
polarity). 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 three
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, type 2A wiring.
¡ñ Standard
configuration extension terminals cover, in
order to protect to use safety, may select
short terminals cover. (Product
Configuration code is TK). |
