▷Product Overview
DDSY8888 type electronic single-phase prepayment meter (the meter) power measurement using microelectronic technology, using fully shielded, hermetically sealed construction, with advanced single-chip processing system for data acquisition, processing and preservation, has good resistance electromagnetic interference, low self-consumption of energy-saving, high accuracy without calibration, anti-theft, high overload, long life characteristics.
Main feature:Application of computer management, after the first purchase of electric power; Within the rated current range can limit the maximum use of power (defined by the electricity sector); A card a table, specifically dedicated card, lost card without losing power, and then fill the card; Electric card can transmit two-way data, can automatically alert users to purchase power; When the power is zero, automatic wind up its power; and has a certain anti-theft software design.
The meter is suitable for a frequency of 50Hz 60Hz active energy metering or installed indoor or outdoor meter box to use. Suitable for ambient temperatures of -25 to + 60?, Relative humidity less than 85%, and ambient air should not corrosive gases, avoiding dust sand, salt spray, condensation and other effects.
The meter in line with GB / T17215.321-2008 and GB / T18460.3-2001 standard technical requirements for single-phase electronic energy meter.

▷Features
● A table and a card: IC card users who have not interchangeable, should be lost to the electricity sector (the sale of electricity at) buy-one.
● Purchase preparation: Before the purchase of electricity, the user shall IC card into the deck once, facilitates the table data back to a computer database.
● Purchase way: when the sale of electricity, the IC card into the IC card reader, simultaneous operation of the computer, the user ID, pre-order power, alarm power, limited capacity and limited capacity power mode encryption, such as written into the IC card.
● Power Card Use: purchase card into the deck, and if so effective purchase card, the meter automatically reads in the data table, LCD display sequentially display table: purchase of electricity, the total available power, frequency meter, alarm battery , on credit limit, limited power capacity. Keep drawing card.
● Operating display: meter running, turn in the table show the remaining charge, the total electricity consumption.
● Ultra-capacity alarm: energy meter is running, if the "alarm indicator" quick flashes, warning users exceeded capacity of electricity. If the meter is set to super-capacity power limit capacity mode, the super-capacity power after 30 seconds, will wind up three minutes, and countdown display (180 seconds) to restore power time; if the card user can respond immediately to restore power .
● Hoarding limit: If purchased the remaining battery power +> hoarding Limited (10000 kWh), the purchase of electricity is not read, the display shows the "remaining charge" prompt, the card power is still valid.
● Warning Alert: When the remaining capacity is less than in the table "Alarm Charge" two times, the "alarm indicator" will flash (1 second interval) displays to remind the user purchase of electricity, this time as a response card support, "the warning indicator" flashing interval becomes 2 seconds, a warning to avoid power outages.
● Off WARNING: If the warning to alert the user when the card is not responding, then when the remaining battery power for the user agreement alarm (or 10% of this electricity purchase), the meter wind up power failure alarm, display "wind up" tips character, this time on the IC card deck that is inserted once power is restored. If you can not find this table after wind up IC card can borrow a neighbor IC card is inserted, to restore power.
● Power Tip: When the remaining capacity is less than the inner "alarm power", the "alarm indicator" is a steady reminder.
● Failure to declare: The remaining battery indicator is zero or negative, the display "wind up" prompt, such as electricity meter continues to run, the user should immediately purchase, and take the initiative to reflect the situation of the electricity sector.
