DDSY1088 single phase electronic prepayment front board installed active
energy meter is a kind of single phase two wire active energy meter
which purchases electricity by IC card, electric energy measuring,
load control and using electricity management. The meter completely
accords 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 single phase AC electricity net, it
is used for setting indoor or out door meter box. This meter has
LED display shows power. It has following features: good
reliability, light weight, specious nice appearance, convenient
※ Standard configuration one meter one card, can repeat input money
from PC machinery
which with IC programmer, may select one-time recharge card.(Please
specified when ordering)
※ It has IC card with code and data against false, standard
configuration use storage IC card, may select
non-contact RF card. (Product Configuration code is PK)
※ Standard configuration payment by kWh, may select payment by
money. (Please specified when
※ Standard configuration of the prepayment management system use of
single version, may select
network version.(Please specified when ordering).
※ It has load control and function of automatic fault detection and
instructions, standard configuration
without function of open terminals cover and detection, may select
open terminals cover and cut power. (Please specified when
※ 6 LED digits display, 5+1 digits display (99999.1kWh), may select
7 LED digits display. (Product
Configuration code isQC).
※ A port of pulse output passive closed(polarity), complying with
standard IEC 62053-31 and standard
※ Two LED instructions signal of energy impulse (red) and direction
of the flow of load current (yellow).
※ Automatic detection the direction of the flow of load current.
When the yellow LED display, that is
meaning the direction of the flow of load current reverse.
※ 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.
※ Direct connect operation, there are two types wiring you may
select. Standard configuration type 1B
wiring, may select type 1A wiring. (Product Configuration code is
※ Front board three fixed installation, standard configuration
short terminals cover, may select extension
terminals cover, in order to protect to use safety. (Product
Configuration code is PA)
1. Each meter has its card all alone, IC cards held by users shall not
exchange. Buy a new IC card from power supply department
(electricity selling place) when losing the card.
2. The way of purchasing electricity: When sells the electricity,
inserts the IC card into the reader-writer, at the same time,
operating the computer, user code, the electric quantity purchased
in advance, alarm quantity of electricity, limits capacity mode and
power and so on being encrypted shall write into the IC card.
3. When using, inserts the IC card into card socket, if it is an
effective IC card, the data will be read into meter automatically,
the LCD display the purchased quantity of electricity, total
purchased quantity of electricity, times of meter, warning quantity
of electricity, limit quantity of credit, limits capacity power in
turn. And IC card shall be preserved properly after removing IC
4. During the operation period, dump energy, total electric quantity
shall be displayed in turn.
5. During the operation period, if the “alarm lamp” blinks quickly,
which warning users that they use the electricity hyper-capacity.
If the mode is set to be hyper-capacity power-cut capacity limit,
and after users use the electricity hyper-capacity for 30 seconds,
it will switch off the power 3 minutes, and displays the time of
restoring the power by count down(180 seconds). If the user inserts
the card, it can restore the power supply.
6. If the electric quantity overflow (purchased quantity of
electricity + dump energy > 10000kWh), purchased quantity of
electricity can not to read in, the LCD displays dump energy, the
electric quantity in the card was still effective.
7. Pre-warning: if dump energy less than twice of the warning quantity
of electricity, the twinkling interval of “alarm lamp” becomes 2
seconds, which can avoid power off warning.
1. The meter shall be installed indoors or in the meter box
2. The meter is suitable for the environment as follows.
3. ambient temperature is -20℃～+50℃.
4. relative humidity are not more than 85％.
5. And the surrounding air shall not contain corrosive gas, and
avoid the influence of dust, salt fog, condensation, etc.
