Type
DEM011TA single phase electronic DIN rail
active energy meter is a kind of new style
single phase two wire active energy meter,
it is fit for use on rental houses, and with
two power energy counters, use for recording
total energy and daily energy. 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. This
meter has LCD display active energy, 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 0106726.X, 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 setting (mounting holes center
distance 67 mm), users can choose any one by
themselves.
¡ñ
Six pole width (Modulus 12.5mm), complying
with standard JB/T7121-1993.
¡ñ
Two 6 digits LCD display, use for display
total energy (5+1 digits display) and daily
energy (4+2 digits display), and we can
cleared the number form the red button on
the panel, the red button can be protected
by lead closed.
¡ñ
Standard configuration LCD display without
backlighting, may select with white
backlighting, and there is maintenance-free
battery, use for display when the power cut
off. (Product Configuration code is TC)
¡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
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 green LED energy pulse signal when
working, that is meaning the direction of
the flow of load current reverse).
¡ñ
Single direction 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
Directly connect operation, there are two
types wiring you may select. Standard
configuration type T wiring, may select type
S wiring (Product Configuration code is ZA).
¡ñ
Standard configuration short terminals
cover, may select extension terminals cover,
in order to protect to use safety. (Product
Configuration code is TB). |
