IC card electric meter DDSY

Main functions:
This energy meter must be recharged by the user's card and entered into the meter before it can provide power. After the electricity in the meter is used up, it will automatically turn off the power, effectively solving the problem of difficult on-site meter reading and electricity collection fees. At the same time, users' electricity purchase information is managed by a microcomputer, making it convenient for querying, statistics, billing, and printing receipts.
This product adopts advanced IC card technology and SMT process, with advantages such as dual display, accurate measurement, stable accuracy, security and confidentiality, reliable performance, complete functions, low power consumption, and simple and convenient operation.
This product can provide IC cards or non-contact IC cards for users to choose from. In addition, this product also offers low-cost single display model products.
Main features:
1. The mechanical character wheel and LED digital tube have dual displays. In the event of a power outage or unexpected malfunction, the mechanical character wheel will still display and there will be no disputes with the user.
2. Transformer free power supply technology, with a power consumption of only 0.4W.
3. Capacity limiting function: The capacity limiting power can be set, and when the load exceeds the capacity limiting power, this product will automatically trip.
4. When there is a remaining 100 degrees, an alarm will be displayed, and when there is a remaining 10 degrees, a power outage alarm will be triggered. The secondary alarm function is unique in China (users can restore power after inserting a card to continue using the remaining battery, and it will automatically power off when used up).
5. Using data voting error correction technology, each data is stored in five places. If there is an error in the data, it can be corrected in four other places, thus achieving absolute reliability and foolproof.
6 All internal components of the IC card energy meter are made of industrial grade branded devices, and key components are made of original chips from the United States and Japan. For example, the measuring chip uses AD7755 to ensure the quality of the device and the entire meter.
7. Non contact IC cards use patented RF card technology to transmit data wirelessly, completely solving the problems of waterproofing, moisture resistance, and attack prevention.
