Smart Card Sinlge Phase Prepaid Energy Meter Sinlge Phase Two Wires
with Remaining Credit Display
DDSY150 series electronic single phase watt hour meter is a high
technology product adople avanced IC technology as well as SMT
technology, both circuit design and componects selectior are up to
various working environment to guaranty that power meter can
operate steadily for a lor time. The finished meter don't neet to
be adjusted so that the calibration cycle is long. It extremely
reduce the labor force of the electricity board for calibrating
power meters. The feature of the products are anti-thief, long
life, high accuracy, high reliability, low power consumption small
volume, light weight, the meter is up to the according to iec
1036-96 and GB/t17215-200 standard.
1. Main Features:
1.1. Standard IC card hardware-based cryptographic for prepayment, the
power supply department receives the electric charge in advance by
means of vending the power utilization card (IC card), and users
should buy first for power utilization.
1.2. It integrates full-digital metering with using electricity power
consuming display, prepayment control, reading card and intelligent
anti-power stolen, ect., has high reliability.
1.3. Function of overload protection. When the load exceeds the preset
maximum current for a continuous period, it would cut off the power
supply circuit automatically, nixie tube would display warning
symbol flickeringly, and the watt-hour meter would switch off
automatically after a certain period of time delay.
1.4. The power utilization IC card is treated with software and
hardware-based cryptographic, guaranteeing safety, correctness and
reliability of data. Through special design, the IC card records
the residual and cumulated electric quantity of meter as well as
information about electricity-stolen if there is while user inserts
the card.
1.5. Perfect card interface protection circuit, preventing hostile
attack behaviors effectively.
1.6. Display of residual electric quantity, it displays in 6-digit (5
integral numbers, 1 decimal number).
1.7. When the residual electric quantity reaches the prep warning
value, nixietube would display the residual electric quantity,
reminding users to input new electricity purchasing quantity.
1.8. When the residual electric quantity in watt-hour meter remains
zero, the watt-hour meter would trip automatically, and cut off the
power supply, at this moment, users must bring the card and go to
power vending department to purchase electricity (power supply
department could set a certain quantity for overdrawing, insert the
card, users could use a certain quantity of electricity), only when
inserting the card with effective electric quantity into the meter
that it could supply power normally.
1.9. The power would be cut off automatically when the owed electric
quantity reaches a certain degree, input new electricity purchasing
quantity (after deducting the over-consumed electricity), the power
supply would be recovered automatically.
1.10. Application of magnetic latching relay not only improves
reliability of power interruption operation, reduces power
consumption after power off, but also conquers the shortcoming of
relay of contacts adhesion when working for long time at heavy
current.
1.11. When coming across power failure, it would store the data
automatically, and resume data at power recovery.
1.12. Computer, special IC card read-write device and charging
management software form the electricity vending management system.
1.13. Carry out comparative analysis to the recorded information, the
management system is able to list out users suspected of
electricity stealing action for concentrated investigation,
reducing the working capacity of anti-electricity stolen and
electricity stolen investigation.
1.14. If the watt-hour meter is reversed connected, it still is able to
meter correctly.

Safety precautions:
＊ Use only isolated tools.
＊ Do not connect the meter to a 3 phase - 415V AC - network.
＊ Place the meter only in dry surroundings.
＊ Make sure the used wires are suitable for the max current the
meter can measure.
＊ Make sure the AC wires are installed correctly before activating
the current/voltage.
＊ Do not touch the meter connecting clamps directly with your bare
hands, with metal, blank wire or other material as you will have
the chance of an electricity shock and a possible chance for health
damage.
