LoRaWAN three-phase rail electricity meter

Introduction:

LoRaWAN three-phase rail electricity meter is a modern instrument designed and manufactured based on the actual power consumption of industrial users, using large-scale integrated circuits and high-precision energy metering chips. Its carrier module communication capability and reliability have also reached a wide range of practical applications, and digital sampling processing technology and SMT process are applied.

LoRaWAN three-phase rail electric meter technical parameters:

(1) Measurement of basic electrical parameters such as three-phase current, three-phase voltage, three-phase power, and frequency, as well as measurement of reactive energy;

(2) Phase sequence error indication of three-phase voltage and current, and power symbol error indication;

(3) Active pulse output indication, communication transmission and reception indication, and reverse phase indication;

(4) Support button setting function;

(5) Setting the direction of current penetration;

(6) After power failure, all stored data will not be lost and can be maintained for more than 10 years;

(7) LORA channel can be set with buttons or communication settings;

(8) Realize interconnection with the collection system through the supporting LOAR gateway device;

(9) LORA interface: adopts voltage CT isolation scheme to ensure that the antenna interface is isolated from the mains power at 2KV or above; The baud rate cannot be set;

(10) Communication protocol: Supports Modbus RTU protocol and some DLT645-2007 protocols;

(11) Appearance: Adopting a guide rail installation shell;

(12) Display format: 8-bit LCD segment code display, supporting cyclic display and button display; 3 LED status indicators;

(13) Installation method: 35mm standard DIN rail shell, flexibly adaptable to various distribution cabinets.

Advantages of LoRaWAN three-phase rail meter:

1. Adopting flame-retardant non-metallic shell, easy to install;

2. Can display positive and negative phase electricity consumption, demand, time, alarm codes, etc;

3. It has a lid opening record function, can be queried, and is anti-theft;

4. Time of use or tiered electricity pricing billing;

5. There are two methods of cost control: remote cost control and local cost control;

6. Capable of RS485 communication and infrared communication;

7. It has the function of resetting the electricity meter, which is convenient and flexible to use.

8. Carrier communication is established through power line networking, without the need for additional cables.
