Application |
Model
DEM311MF single phase electronic front board
installed active energy meter is 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 this meter
has seven digits LCD displays shows the
active energy consumption. And there is a
maintenance-free lithium battery in it, use
for displaying power cup 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.
¡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 battery
in it, use for showing blackout 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 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 pulse
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 of load current. Complying with
standard IEC 62053-21.
¡ñ
Direct connect operation, there are two
types wiring you may select. Standard
configuration type 1B wiring, may select
type 1A wiring (Product Configuration code
is DS).
¡ñ
Standard configuration extension terminals
cover, in order to protect to use safety,
may select short terminals cover. (Product
Configuration code is MC).
