DDSY6111 single-phase prepaid electricity meter (1st generation property version IC card plug-in energy meter)

DDSY6111 electronic typeDDSYAdopting integrated circuit design, fully automatic surface mount（SMT）Production process manufacturing. The circuit design and component selection of the electric energy meter are based on a large environmental tolerance, which can ensure stable operation of the whole machine, high accuracy, high overload, low power consumption, and high reliability performance.Built in magnetic holding relay. By controlling the relay to control the on and off of the load, the function of urging users to buy electricity before using it can be achieved.

Key Features:

1. Apply computer management to purchase electricity before using it; The power usage can be limited within the rated current range (limited by the power supply department); One meter, one card, dedicated card, no power loss after card loss, can be used after card replacement; Electric cards can transmit data bidirectionally and automatically power off to alert users when purchasing electricity; When the amount is zero, the power will automatically trip and cut off; And it has certain anti-theft software design, etc.

2. The electricity meter displays the remaining amount, total electricity consumption, etc.

3. Each computer has an independent serial number, which provides strong anti-theft capabilities.

4. Before inserting the "user card", you need to first insert the "settings card" to make all the electricity meters recognize your electricity sales system for anti-theft purposes.

5. The electricity meter can be reset to zero by simply inserting the "reset card".

6. Electricity, property management, rent, and other fees can be collected. The electricity fee is0Automatic power outage, at this time, if the property fee or rent fee expires, the electricity sales system will prompt for recharging during charging.

7. When selling electricity, the user card can be directly charged in the system and then plugged into the meter for use.

4、 Installation and use

1. The electricity meter has been inspected and qualified before leaving the factory, and sealed with a lead seal before installation and use. If there is no lead seal or it has been stored for too long, relevant departments should be asked to re verify and seal it before installation and use.

2. The electric meter should be installed in a dry and ventilated place, and the bottom plate for installing the electric meter should be fixed on a sturdy, fire-resistant, and non vibrating wall. The height of the electric meter should be about1.8mabout.

3. Install and wire according to Figure 1 and Figure 2, tighten the wiring screws, and secure the connecting plate inside the terminal box.

4. The reading of an electric meter connected through a transformer must be multiplied by the transformation ratio to obtain the actual amount of electrical energy.

5. One table, one card: held by the userICCards cannot be exchanged. If lost, please go to the power supply department(Electricity sales office)Purchase an additional one.

6. Preparation for purchasing electricity: Before purchasing electricity, users mustICInsert the card into the card slot once to facilitate sending the data in the table back to the computer database.

7. Electricity purchase method: When selling electricity, theICCard insertionICCard reader/writer, simultaneously operating the computer to encrypt and write user ID, pre order amount, alarm amount, capacity limit method, and capacity limit power, etcICCard.

8. Electricity card usage: Insert the power purchase card into the card slot. If it is a valid power purchase card, the meter will automatically read the data into the meter. The LCD display screen will show the remaining amount, power purchase amount, total purchase amount, total power consumption, user number, and constant in sequence. Please keep the card properly when unplugged.

9. Operation display: During the operation of the electricity meter, it alternately displays the remaining amount, purchase amount, total purchase amount, total electricity consumption, user number, and constant in the meter.

10. Overcapacity alarm: During the operation of the electricity meter, if the "alarm indicator light" flashes rapidly, it warns the user that the electricity has been exceeded. If the meter is set to the over capacity power-off limit mode, then the over capacity electricity will be used60In seconds, the brake will be pulled3minute; If the user inserts the card and responds, the power supply can be immediately restored.

11Accumulation limit: If purchased electricity+remaining electricity>Accumulation limit（10000kWh)If the purchased electricity is not read in, the display will show“Error=10

”Reminder: The battery level in the card is still valid.112

Warning reminder: When the remaining amount in the table is less than the "sound and light alarm amount", the "alarm indicator light" will flash (with an interval ofDisplay a reminder to the user to purchase electricity in seconds.13. Power outage warning: When the remaining amount in the meter is less than the "trip alarm amount", the "alarm indicator light" will remain on, and the LCD will display the "trip" prompt. The relay will trip. At this time, the user can insert the power purchase card into the meter once, and the meter will close. The "alarm indicator light" will continue to stay on. At this time, the user should quickly go to the power supply department to purchase electricity to avoid being unable to purchase electricity in a timely manner and unable to use electricity. If this table cannot be found after pulling the switchICCard, can be borrowed from neighbors

IC

Insert the card to restore power supply.

Power purchase reminder: When the remaining amount in the meter is less than the "alarm amount", the "alarm indicator light" will remain on as a constant reminder.
