DDSY Prepaid Metering System Single Phase IC Card Meter With Pulse Output

DDSY Prepaid Metering System Single Phase IC Card Meter With Pulse Output

DDSY series single-phase prepayment kwh meters are new IC card type prepaid electric energy meters with multiple functions of electric energy and load control and user location management, etc., researched and developed based on our company's electronic type single-phase electric energy meter of excellent performance.

The meter is an ideal product under the current reform of electricity system to achieve electric energy commercialization, solve the difficulty in charging and adjust the grid load state. All performance indicators of this product conform to IEC technical standards.
 

Function and features

• Metering active electric energy, without the need of tuning for long-term work;
• One meter (household) one card, multiple encryption, with good anti-counterfeiting;
• When the remaining electric quantity is equal to the alarm quantity, the indicator lights to remind users of timely purchase;
• Trip and power off when the remaining electric quantity is 0;
• Prevent electricity larceny and record illegal electricity consumption information automatically;
• Overload automatic power-off facilitates the power sector to implement capacity increase;
• Large-capacity magnetic latching relay, with low power consumption and high reliability;
• With data write-back function, it is easy for the management of power sector;
• As long life and high reliability electronic components are selected for all the components inside the meter, the meter has;
• Characteristics of long life and high reliability;
• The supporting IC card electricity sale management system has the functions of complete electricity sale management, electricity consumption monitoring, etc.;

 Main Features: 

• Pay As You Go: IC card that adopts " Financial Card Project" hardware encryption technology is used by the Power Company to collect the electricity fee in advance.
• High Reliability: the meter is combined with fully-digital metering, kWh display, prepayment control, card reading and smart anti-theft technique .
• Overload Protection: the meter will cut off the power supply circuit automatically when the load exceeding about 20%~30% of rated Max. Current lasts for 10~15s;
• High Security And Accuracy: the IC card is used multiple encryption via hardware and software to ensure data safety, accurate and reliable. The special design of IC Card is that it can record the the information about remaining electricity fee, accumulated electricity when the User insert it into the meter and also can reflect power stealing action.
• Perfect Interface Protection: the meter has the capability to protect circuit against malicious attacks.
• Scrolling Display: the show time of different metering parameters is 10s for residual electricity fee (Two decimals, CNY), 5s for unit price, 5s for accumulated power consumption (One decimal, kWh) and 5s for the current power consumption (One decimal, kWh)
• Easy-To-Read: The total and unit price of electricity inside the meter is accumulated in the unit of four decimals and CNY.
• Has the feature of partition management.
• Supports for max. hoarding electricity quantity and alarm mode.
• Magnetic Latching Relay Applied: it can improve the performance of outage movement and lower the power consumption after power failure, and meanwhile, also can get rid of the contactor adhesions when the relay is being worked under the large current for a long time.
• The meter will keep data or get recovery when being powered on./off automatically.
