Electronic cards, also known as IC cards or power purchase cards, are made by specially packaging dedicated IC chips. Common power purchase cards are divided into touch and non touch types according to communication methods. Single phase energy meter, used for active power measurement: accurate measurement modular small volume (18mm), can be easily installed in various terminal distribution boxes. Rail mounted installation, bottom wiring, perfectly matched with miniature circuit breakers. Intuitive and easy to read mechanical display reduces the risk of data loss due to unexpected power outages. No external power supply is required for the job. The temperature range for homework is wide.

Prepaid three-phase remote transmission electric meterAlso known as a quantitative energy meter or IC card energy meter, in addition to having the measuring function of a general energy meter, it is particularly important for users to buy electricity first and then use it. If the user does not continue to buy electricity after using it up, the power supply will be automatically blocked and interrupted. Prepaid energy meters, also known as quantitative energy meters or IC card energy meters, not only have the measuring function of general energy meters, but also require users to buy electricity first before using it. If the user does not continue to buy electricity after using it, the power supply will be automatically blocked and interrupted. Used for measuring AC single-phase active energy with a rated frequency of 50Hz, completing the function of paying before using electricity. Select advanced microelectronics technology for data collection, processing, and storage, and use RF cards to transmit data. Its performance indicators comply with GB/T17215-2002 and GB/T18460.3-2001 standards. It has the characteristics of small size, high reliability, and anti electricity theft.
