Application |
Model
DEM315BS 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 1A wiring, may select
type 1B
wiring (Product Configuration code is GF).
¡ñ
Standard configuration extension terminals
cover, in order to protect to use safety,
may select short terminals cover. (Product
Configuration code is BR). |
