Model
DEM101QG three phase four wire electronic prepayment front board
installed active energy meter is a kind of
three phase four
wire active energy meter which purchase electricity by IC card, electric
energy measuring, load control
and using
electricity management. 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
accurately and directly measure
50Hz or 60Hz active
energy consumption from three phase four wire AC electricity net, it is
use for install in meter box
indoor or out door.
This meter has LCD monitors shows power. It has following features: good
reliability, light weight,
specious nice
appearance, convenient installation, etc.

--A
port of pulse output passive closed (polarity), complying with
standard IEC 62053-31 and
standard DIN 43864.
--Five
LED instructions power state, signal of power impulse and direction
of the trend of
load current.
--Automatic
detect the direction of the trend of load current. When the yellow
LED display,
that is meaning the current reverse.
--Single
direction three component measure three phase four wire active
energy
consumption. It is nothing with direction
of
the trend of load current. Complying with
standard IEC 62053-21.
--Direct
connect and use, type 16B connection, may select three phase three
wire, direct
connect operation, type 13B connection
(Product Configuration code is QH).
--Front
board three fixed holes installation, standard configuration short
terminals cover, you
may select extended terminals cover, in order to
protect to use electricity safely. (Product
Configuration code is QE). |
