Application |
Model
DEM312AG single phase electronic front board
installed active energy meter is a kind of
new style single phase two 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 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 is use for setting indoor or out
door, and 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 AK).
¡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 1B wiring, may
select type 1A
wiring (Product Configuration code is TG).
¡ñ
Standard configuration
short terminals cover, may select extension
terminals cover, in order to protect to use
safety. (Product
Configuration code is AH). |
