Three-phase electronic prepaid electricity meter
Other Products
The three-phase electronic prepaid energy meter is a new type of IC card prepaid energy meter with various functions such as energy measurement, load control, and user information management. It is an ideal product for reforming the electricity system, commercializing electric energy, solving payment difficulties, and regulating grid load conditions. This series of three-phase electronic prepaid energy meters has two connection methods: direct connection or via transformer connection.
Performance Features:
▼ Measures three-phase active energy, uses long-life components, has a long service life, and requires no calibration during long-term operation;
▼ Powered by three-phase supply; accuracy of measurement remains unaffected even if one line (any one or two lines in a three-phase three-wire meter, or any two lines in a three-phase four-wire meter) is disconnected;
▼ Features phase failure indication and voltage indication functions;
▼ Uses imported memory. Data can be retained for over ten years without loss during power outages;
▼ Has energy test signal output;
▼ One meter (household) per card, ensuring excellent anti-counterfeiting;
▼ The recharge card uses SLE4442 encrypted IC card, each with a random password to prevent imitation and forgery;
▼ When the remaining power equals the alarm level, the indicator light turns on to remind the user to recharge in time; when the remaining power is 0, the power is cut off by tripping;
▼ Automatic power cut-off in case of overload, facilitating capacity expansion by the power department;
▼ Features data write-back function, expandable RS485 communication for remote centralized meter reading, facilitating management by the power department;
▼ The load switch is installed outside the meter, with relay control inside (contact capacity 250VAC/5A), or built-in relay for power cut-off control;
▼ The accompanying IC card power sales management system has comprehensive functions for power sales management and electricity supervision.
