Besides measure active energy, it also has function for online power display, smart anti-tamper, overload control, remote meter reading and etc. It sends data to corresponding gateway through LoRaWAN wireless network. It has advantages in high accuracy, low power consumption, and good stability that can be widely used for the single phase alternating current in city, rural areas or factory enterprises, etc.Product Parameters:Technical data:Function module:Communication interface: LoRaWAN communication mode, RS485 protocolEnviroments :Normal working temperature: -25ºC~ +55ºCLimited working temperature: -45ºC~ +70ºCRelative humidity: <=85%Basic information:Overall Power Consumption: <1.0WStarting current: ≤0.004 IbOverall dimensions: 154mm×110mm×60mmWeight: 0.5kgOperating life: >10 yearsProduct Functions:1. High Precision measurement of voltage , current , active power , reactive power , apparent meter , power factor , frequency2. Provide the digital tube display , local data query3. Support LoRaWAN RS485 communication.Composition theory:The voltage/current sampling circuit samples the voltage of the power grid and the current flowing through the electric meter, sampled voltage and current signals are multiplied to obtain a power value, and then integrated according to time to obtain electric energy. Smart energy meter measure the energy through output CF pulse counting, after electric meter corrects the error, only the CF pulse is counted to obtain the electric energy which is saved by the storage. The microprocessor simultaneously performs the functions of displaying and exchanging information with external device. Its principle block diagram is shown in Figure 1.Operation, debug and installation1) No need for extra operation and debug after leaving factory, can be in normal use since finished installation by professional person.2)Before installation, please check manufacture's seal is in good condition.3)Meter should be installed indoor or on the fire-proof wall outdoor, the height is about 1.8m, no corrosive gas in the air.4)Meter should follow the connection diagram, using copper wire or copper terminal clamp for input.5)Main terminal connection6) Main and auxiliary terminal connectionMain terminal connection follows Figure 2, 1 as L In, 2 as L Out, 3 as N In, 4 as N Out. There are 4 auxiliary terminals on the top of main terminal, in which 7 & 8 as measure pulse output.vLoRaWAN communication interface:Using LoRaWAN communication for meter reading and parameter setting. When meter reading, remote meter data transmission software provided by our company can be used for meter reading and parameter setting. It is also possible to design a software and hardware system that fully complies with the protocol requirements for meter reading and parameter setting according to the power industry standard DL/T 645-2007 (supporting part of the communication protocol).Company Introduction:Wuhan Radarking Electronics Corp. is a modern share enterprises which focusing on the smart Internet of things(IOT) /smart grid energy consumption sensor/intelligent electric safety integrated solution. It established in 2002(former name: Wuhan Radarking Co.,Ltd.)and went public on January 27, 2015 with the stock abbreviation RADARKING and stock number 831722. It owns the independent R&D center and factory which is the key recommended high-tech enterprises in Wuhan city.It mainly R&D, manufacture and sell the integrated solution of smart Internet of things(IOT) energy consumption sensor/smart grid energy consumption sensor/energy consumption information acquisition and transmission(Collector, Concentrator, Communication Module), smart electric meter, smart water meter, "RDK" energy Internet of Things(IOT) intelligent energy safety integrated solution, digital campus energy consumption acquisition(meter reading) charging management integrated solution, 4-in-1 Meter energy consumption acquisition(meter reading) charging management integrated solution, 4-in-1 Meter/All-in-One Card cloud computing total charging management integrated solution, energy consumption monitoring and analysis integrated solution, mobile phone APP(Energy Consumption, Fast E Top Up).Principle:It pursues "Military Academy, Military Morality, Character, Integrity"business philosophy. According to the " Success once at a time, Advance and reliable, Customer satisfaction, Continuous improvement" quality policy, produce the military high standard products depend on the talent and technology advantages. By military character, do the man first and then work, and provide the high quality products and favorable service to the domestic and overseas clients.
