Application |
Model
DEM313DS 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 setting
out door directly, and this meter has seven
digits LCD displays shows the active energy
consumption. And there is a maintenance-free
lithium batteries in it, use for displaying
power cut reading. 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, the
cover is made of PC material which is
transparent and anti-UV molded overall, the
bottom and the terminal of the meter are
made of black glass fiber which can
fire-retardant and enhanced PC material, and
the
IP rating up to IP56. It has following
features: good weather
ability, anti-impact, good insulation
performance, specious
appearance, etc.
¡ñ
Standard configuration the bottom and the
terminal of the meter are closed by the
screw of the meter, may select the bottom
and the terminal of the meter are closed by
ultrasonic. (Please specified when
ordering).
¡ñ
Seven digits display LCD, standard
configuration 6+1 digits display
(999999.1kWh,). May select 5+2 digits
display (Please
specified when ordering).
¡ñ
There is a maintenance-free lithium
batteries in it, use for displaying power
cut reading.
¡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 respectively power
supply state (green) and signal of energy
impulse (red).
¡ñ
Automatic detection the direction of the
flow of load current. And Instructions on
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
measurement 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 1A wiring, may select
type 1B
wiring (Product Configuration code is MF).
¡ñ
Standard configuration extension terminals
cover, in order to protect to use safety,
may select short terminals cover. (Product
Configuration code is DR). |
