Application |
Model
DEM315GC 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 out
door, and this meter has seven digits LCD
displays shows the active energy
consumption. And there are far infrared and
RS485 communication module in it. Contact
with all kind of AMR system conveniently. 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
of the meter and the terminal is made of
bakelite material quality which is
moisture-resistant, fire-retardant, high
temperature
molded overall. It has following features:
Good weather
ability, high rigid, excellent dielectric
strength, etc.
¡ñ
May select 6+1 digits display (999999.1kWh,
default) or 5+2 digits display, it can be
arbitrary set by users from far infrared or
port
of RS485 data communication.
¡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
There are a port of far infrared data
communication and a port of RS485 data
communication. Standard configuration
communication agreement complying with
standard DL/T645-1997, can also choose any
other communication agreement.
¡ñ
Three LED instructions power supply state,
signal of energy impulse and communication
state.
¡ñ
Automatic detection the direction of the
flow of load current. And instructions by
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 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 BR).
¡ñ
Standard configuration short terminals
cover, may select extension terminals cover,
in order to protect to use safety. (Product
Configuration code is GF). |
