Model
DEM312AH
Single Phase
electronic kWh electricity meters 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 accurately 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 type impulse
register. It has following features:
good reliability,
small volume, light weight , specious nice appearance, convenient
installation, etc.

Single Phase electronic kWh electricity meters
Function and features: |
|
-Single
Phase electronic kWh electricity meters- Front
board three fixed holes installation, up and down mounting holes
center distance
is130-147 mm, users can choose
any one by themselves.
-Single
Phase electronic kWh electricity meters-Standard
configuration 5+1 digits display (99999.1kWh) by step motor and
pulse
machinery counter. May select 6+1 digits
display (Product Configuration code is SC).
-Single
Phase electronic kWh electricity meters-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.
-Single
Phase electronic kWh electricity meters-Two
LED instructions power state (green) and signal of power impulse
(red).
-Single
Phase electronic kWh electricity meters-Automatic
Detect the direction of the trend of load current. And instructions
by individual
LED. (Only yellow power pulse
signal when working, that is meaning the load current
reverse).
-Single
Phase electronic kWh electricity meters-Single
direction single component measure single phase two wire active
Power. It is
nothing with direction of the trend
of
load current. Complying with standard IEC 62053-21.
-Single
Phase electronic kWh electricity meters-Direct
connect and use, there are two type you may select. Standard
configuration type 1B
connection, may select type
1A connection (Product Configuration code is TH).
-Single
Phase electronic kWh electricity meters-Standard
configuration extended terminals cover, may select short terminals
cover, in
order to protect to use electricity
safely. (Product Configuration code is AG). |
