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.
