Application |
Model
DEM041HL two phase three wire electronic
multi-rate DIN rail active energy meter is a
kind of two phase three 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
three phase active energy meter stipulated
in international standard IEC 62053-21. It
can accurate and directly measure 50Hz or
60Hz active energy consumption from two
phase three wire 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 0107349.1, any
other country patent certificate are in
assessing.

¡ñ
Eight LED instructions respectively power
supply state, signal of energy impulse, the
direction of the flow of load current, the
tariff state just now and the data
communications state.
¡ñ
Single direction two components measure two
phase three 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
