Introduction:

Three phase four wire prepaid electricity meter, using large-scale integrated circuits, applying digital sampling processing technology and SMT process. High reliability, high precision, and high sensitivity. Long lifespan, low power consumption, no need for verification throughout life. Equipped with M-BUS RS-485、 The infrared PLC communication interface is optional and can achieve remote meter reading.

The management department can design and manufacture modern and advanced instruments based on the actual electricity consumption of users. Its purpose is to measure three-phase AC active energy with a frequency of 50Hz, and to complete the prepaid electricity management function of buying electricity before using it. It is an ideal product for China's reform of the electricity system and the commercialization of electricity.

Introduction to the functions of three-phase four wire prepaid electricity meter:

(0) Anti electricity theft: One meter and one card cannot be copied, which can effectively prevent electricity theft.

(0) Maintenance free: Active power metering, no adjustment required for long-term operation.

(0) Dual display function: Compare and measure mechanical and electronic measurements.

(0) Multi functional metering: It can accurately measure active power in both positive and negative directions.

(0) Anti destructive ability: It has strong anti-interference ability, and the card holder is internally measured when damaged.

(0) Data write back: The power purchase card has the function of automatically writing back various user data.

(0) Alarm function: When the remaining power is less than the alarm power, the meter will always display the remaining power to remind the user to purchase electricity.

(0) Automatic power-off: When the remaining power in the energy meter is zero, the energy meter automatically trips and interrupts the power supply.

(0) Power inquiry: Insert the IC card to display the total purchased power, number of power purchases, last purchased power, cumulative power consumption, and remaining power in sequence.

(0) Prepaid function: By using the 4428 logical encryption card, payment can be made before use, which is convenient for management.

(0) Data protection: Data retention time after power outage is ≥ 10 years.
