The prepaid energy meter
adopts advanced metering chip for accurate measurement; it uses digital calibration technology without any physical adjustment components and high stability; it pays for electricity
before paying, which effectively prevents the problem of arrears in electricity bills. Ideal product for energy metering. The technical indicators all comply with GB / T17215-2002 standard and GB / T18460-2001 standard.
Functions and features
1, strong anti-theft, anti-electromagnetic interference ability.
2. Stable performance, high accuracy and low power consumption.
3. Remaining battery alarm: often display alarm and power failure alarm.
4. Single-phase card meters and three-phase card meters can share a management system.
5. High-reliability magnetic holding relay, wide range and strong overload capacity.
6. The digital tube or LCD screen displays the remaining power and power consumption status.
7, using the encryption card and DES dynamic encryption algorithm, the data is reliable and will not be cracked.
8. The IC card transfers data in two directions, one card per meter, data is lost if the card is lost, and the card is re-used, and the original card is automatically lost.
9. Stable, reliable, long-term work does not need to be adjusted, and the data in the meter can be stored for a long time after power failure.
10. Active power can be measured in both positive and negative directions.
The single-phase prepayment meter uses microelectronics to measure electrical energy. The product has a reasonable design and complete functions. The energy meter uses an advanced single-chip processing system for data collection, processing, and storage. Long life and other characteristics, its outstanding feature is to pay money first and then use electricity, completely solve the problem of difficult to charge electricity meters. The pre-payment management software is rigorous in design and easy to use, which has won the trust of the power management department. The technical indicators all comply with GB / T17215-2002 standard and GB / T18460-2001 standard.
The single-phase pre-paid meter digital tube displays the remaining power and internal parameter information of the meter. Using encryption card and DES dynamic encryption algorithm, the system data is reliable. The function of writing back the meter parameters after inserting the card is rigorous in design and will not cause power disputes. High accuracy, stable performance, low power, anti-theft, long-term use without adjustment. When the remaining power is not large, it has two levels of alarm functions: constant display alarm function and power failure alarm function to remind users to purchase power in a timely manner.
Load control function: When the load exceeds the set value, the meter will automatically power off, and the meter will automatically resume power supply about 5 minutes after the load is reduced. Card function: can be used with water meter, gas meter and heat meter to achieve one card.
Pre-paid energy meters
use microelectronics to measure electrical energy. The product design is reasonable and the functions are perfect. Users are welcome to call for consultation.
