Model
DEM341FM three phase three wire electronic multi-rate front board
installed active energy meter is a kind of three
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 accurately and directly measure 50Hz or
60Hz active energy consumption from
three phase three
wire AC electricity net, it is use for installed in meter box indoor or
out door. This meter has seven digits
LCD monitors shows
various consumption data and information. It has following features:
Good reliability, light weight,
specious nice
appearance, convenient installation, etc.

Function and features: |
|
-- Front
board three fixed holes installation, up and down mounting holes
center distance is
198-212 mm, users can choose any one by themselves.
--Have two tariffs, and port of set the tariff, input control
voltage 0-90 Vac, set up tariff F1,
input control voltage 150-400 Vac, set up tariff F2,
the tariff conversion is controlled by timer
outside
or similar equipment.
--Standard
configuration cycle display every 5 second, it can display 6 data at
most. Can
select the data which displayed.
The decimal median which displayed can choose set
one or two. (Default two decimal, please specified
when
ordering)
--Use memory that is not loss easy, the data can be kept forever
after power cut off.
--There is a polarity port of
pulse output passive closed and a no polarity port of pulse
output
passive distant, the output rate
is 10 or 100 imp/kWh (can select),Complying with
standard IEC 62053-31 and DIN 43864.
--Seven
LED instructions respectively power state, signal of power impulse,
the direction of
the trend of load current, the state
rates just now.
--Single
direction three components measure three phase four wire active
power
consumption.
It is nothing with direction of the
trend of load current. Complying with
standard IEC 62053-21.
--Standard configuration for direct connect and use, type 16B
connection, we can also
choose another type of connection,
and use CT (Product Configuration code is FO) and
PT & CT (Product Configuration code is FQ, type 48B
connection
for operation.
--Standard
configuration short terminals cover, may select extended terminals
cover, in
order to protect to use electricity
safely. (Product Configuration code is FL). |
