Model
DEM031BL single phase electronic multi-rate
DIN rail active energy meter is a kind of
single phase two wire two tariffs (tariff
conversion is controlled by timer outside or
similar equipment) active energy meter. 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. This meter has seven
digits LCD displays shows various
consumption data and information. And there
are far infrared and RS485 communication
module in it. It is use for setting and
reading the meter. Contact with all kind of
AMR system conveniently. 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
0106828.1, any other country patent
certificate are in assessing.

complying with standard IEC 62053-31.
¡ñ
There are far infrared and a port of RS485
communication data. It is use for setting
and reading the meter, communication
agreement complying with standard
DL/T645-1997.
¡ñ
Six LED instructions respectively power
supply state, signal of energy impulse, the
direction of the flow of load current, the
state rates just now and the data
communications state.
¡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
Standard configuration type S wiring (Inlet
from bottom, outlet from top) for direct
connect operation, we can also choose
another type of wiring, and use CT (Product
Configuration code is BN) and PT & CT
(Product Configuration code is BP) for
operation.
¡ñ
Standard configuration short terminals
cover, may select extension terminals cover,
in order to protect to use safety. (Product
Configuration code is BM). |
