Our company has many years of experience in electric meter design and launches new smart meters, with the option of RS485、NB-LOT（5G）、4G、WIFI、 Bluetooth, ROLA、 Communication via carriers and other means.This series of instruments has the advantages of small size, high accuracy, good reliability and easy installation. The performance indicators comply with the national standards GB/T17215、GB/17883various technical requirements.
Electronic single-phase prepaid electricity meter, designed with a dedicated integrated circuit, fully automatic surface mount ( SMT） Production process manufacturing.The circuit design and component selection of the power meter are based on large environmental tolerances, which can ensure the long-term and stable operation of the entire machine, with good electromagnetic interference, low power consumption, high precision, anti-power, high overload, long life, and high reliability and high performance.Adopt advanced intelligence that meets international standards IC Card technology realizes prepaid method and has built-in magnetic retention relay.Control the on and off load by controlling the relay, and realize the function of urging users to buy electricity first and then use electricity.。
1. Prepaid: Users purchase power with a card, the remaining electricity bill is 0, and the power is automatically cut off.
2. One table and one card: held by users IC Cards cannot be interchangeable, and you should go to the power supply department if they are lost.(Power Sales Office )Buy one more.
3. Operation display: During the operation of the meter, the remaining power and total power consumption in the meter are displayed in turn.
4. Ultracapacitance alarm: During the operation of the meter, the power consumption exceeds the power and the meter will automatically be powered off.Pull the switch for 3 minutes and countdown display (180Second )Restore power supply time;If the user responds to the card, the power supply can be restored immediately.
Power off warning: If the user does not respond when the card is reminded and an overcapacity alarm is set, when the remaining power is the user's agreed alarm power (or the amount of power purchased this time)10％）When the meter is shut down and the power outage warning will be IC If you plug it in the card holder, you will restore power supply.
5. Support self-service payment machine mobile payment (optional)
6. Supports multi-rate (peak flat valley) electricity prices, ladder electricity prices (optional)
7. Support 485 communication (optional)
