Introduction:

The NB-IOT prepaid electricity meter adopts advanced application specific integrated circuit design and is manufactured using fully automatic surface mount (SMT) production technology. The circuit design and component selection of the electric energy meter are based on a large environmental tolerance, which can ensure long-term stable operation of the whole machine, high precision, high overload, low power consumption, and high reliability performance. Adopting advanced intelligent IC card technology that meets international standards to achieve prepaid payment, with built-in magnetic holding relay. By controlling the relay to control the on and off of the load, the function of urging users to buy electricity before using it can be achieved.

NB-IOT prepaid electricity meters are intelligent terminals and basic equipment in the entire electricity sales market, especially in scenarios such as hospitals, schools, rental housing, and nine small places, forming a huge market and playing an indispensable development potential in the entire electrical industry.

NB-IOT Prepaid Electric Meter Technical Parameters:

NB-IOT prepaid electricity meter function introduction:

(1) Display meter reading: By pressing the buttons on the meter, the monthly total electricity, voltage, current, power factor, and other data of the meter can be queried on the LCD screen.

(2) Communication meter reading: Through RS485 communication port meter reading and handheld infrared meter reading machine, combined with meter reading system, various electricity data of the meter can be read. And supports DL/T645-1997 multifunctional energy meter communication protocol.

(3) Ladder billing: Setting different electricity price structures based on the needs of various categories and the different requirements reflecting the composition of power supply costs, known as peak and valley metering.
