Application |
Model
DEM312AH 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 SC).
¡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 load current.
Complying with standard IEC 62053-21.
¡ñ Direct connect
operation, there are two types wiring
select. Standard configuration type 1B
wiring, may select type 1A wiring
(Product Configuration
code is TH).
¡ñ Standard
configuration extension terminals cover, in
order to protect to use safety, may select
short terminals cover. (Product
Configuration code is
AG). |
