Smart prepaid electricity meter

This product adopts advanced non-contact RF card technology and SMT process to manage users' smart meters with one card at a time. It has the advantages of accurate measurement, high accuracy, security and confidentiality, reliable performance, rich functions, low power consumption, and simple operation. The product complies with the standards of GB/T17215.321-2008 "Level 1 and Level 2 Static AC Active Energy Meters" and GB/T18460.3-2001 "Prepaid Energy Meters", and is particularly suitable for electricity metering and control in residential areas, apartment users, building offices, enterprises and institutions.

Features

◆ RF induction control to prevent malicious damage.

Strong ability to prevent electricity theft and electromagnetic interference.

◆ Stable performance, high accuracy, and low self power consumption.

The electricity meter and water meter can share one RF card and the same management system.

Using RF card and DES dynamic encryption algorithm, data is secure and reliable.

◆ Adopting high-power and high reliability magnetic holding relays, with a wide range and strong overload capacity.

◆ Prepaid function: Pay first before using electricity, automatically cut off power when there is no fee, and automatically restore power after paying and swiping the card.

The IC card transfers data bidirectionally, with one meter and one card. If the card is lost, the data will not be lost. When a new card is used, the original card will be automatically invalidated.

◆ Power outage alarm function: When the remaining power reaches the alarm value, the electricity meter will automatically power off to remind users to purchase electricity in a timely manner. After swiping the card, users can continue to use electricity until the remaining power reaches zero and the electricity meter will power off again.
