Application |
Model
DEM461AH single phase electronic DIN rail
anti-steal 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 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.
This meter has already got the patent
certificate from China State Intellectual
Property Office at present. Patent
certificate NO. ZL 2006 3 0106828.1, any
other country patent certificate are in
assessing.

Functions and
features |
¡ñ
35mm standard DIN rail installation,
complying with standard DIN EN50022. Or
front board installed (mounting holes center
distance 63 mm), users can choose any one by
themselves.
¡ñ
Six pole width (Modulus 12.5mm), complying
with standard JB/T7121-1993.
¡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
Three LED instructions power supply state
(green) and signal of energy impulse (red)
and signal of fault (yellow).
¡ñ
Standard configuration don¡¯t detection
direction of the flow of load current. May
select automatic detection the direction of
the flow of load current. And instructions
(Only red energy pulse signal when working,
that is meaning the direction of the flow of
load current reverse).
¡ñ
Single direction two components 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
Automatic detection the current of phase
line and neutral line, get the higher value
of the current and calculation, when the
error of the two current more then 12.5%,
automatic show fault signal.
¡ñ
Direct connect operation, there are two
types wiring you may select. Standard
configuration type S wiring, may select type
T wiring (Product Configuration code is TH).
¡ñ
Standard configuration short terminals
cover, may select extension terminals cover,
in order to protect to use safety. (Product
Configuration code is AG). |
