Product Introduction: Prepaid electric energy meter is also called quantitative electric energy In addition to the measuring function of ordinary electric energy meters, meters and card electric energy meters have the special feature that users buy electricity first and then use it. If the user does not continue to buy electricity after using up the electricity, the power supply will be automatically cut off. The advantage of the card energy meter is that it does not require manual meter reading, which is conducive to modern management. The use of card meters avoids the inconvenience caused to customers by manual meter reading and door-to-door charging, and historical power purchase data can be saved for easy query by customers. It fully reflects the commodity attributes of electricity. By implementing the policy of buying electricity first and then using it, customers can purchase and use electricity in a planned manner according to their actual needs, without late payment fees or unnecessary expenses due to arrears. Solved the problem of difficulty in charging. It can well solve the charging problems of scattered residential customers, temporary electricity customers, and customers with frequent arrears. The card energy meter has a variety of anti-stealing functions, such as small starting current, no creeping, wide load, low power consumption, flat error curve, good stability during long-term operation, beautiful appearance, small size, light weight, and easy installation. High accuracy: fully electronic design, built-in imported special chip, accuracy is not affected by frequency, temperature, voltage, and high-order harmonics. Long life: Using advanced technology and optimized circuit design, there is no need to adjust the circuit after the whole machine leaves the factory. Low power consumption: Adopt low power consumption design to reduce power grid line loss. The pre-purchased power card transmits data to realize data readback, including: reading back information such as total power, remaining power, accumulated power purchased in the meter, total number of power purchases, etc. Store table constants, initial values, user addresses, names and other information. Overload alarm, power outage, and remaining power alarm remind users to purchase electricity in time. Technical parameters: Use long-life base meter to extend the service life. Main features:: Using contactless card technology, waterproof, moisture-proof, dust-proof, wear-resistant, and resistant to external electromagnetic attacks. Adopt display. : The single-chip microcomputer and non-volatile memory adopt imported components to ensure the reliability, ease of use and safety of the product. : Cards from different users do not work in each other's energy meters. Cards from different power supply departments cannot be used universally. : The card transmits data in both directions, and the electricity consumption data in the meter is returned through the card to facilitate management. : When there is reverse connection and electricity theft, the electricity consumption will also be recorded, which has a certain anti-electricity theft function. : The one-card electric meter also has one-card technology. One contactless card can be used for individual electric energy meters or other one-card smart meters of the company.
