Introduction:

The rail type IoT meter adopts a shielded and sealed structure, and uses a single-chip microcontroller for data acquisition, processing, and storage. Has good resistance to electromagnetic interference, low power consumption, high accuracy, high overload, and long lifespan. System application computer management, purchase electricity first and then use it. Can provide load limiting control according to user requirements. It can also expand auxiliary functions through its communication interface to achieve DI DO、 Temperature measurement, residual current measurement, as well as 2G, 4G, LoRa, LoRaWan, NB Lot wireless communication functions.

Technical parameters of rail type IoT electric meter:

(1.1) Accuracy level 1.0, 2.0;

(1.2) Rated voltage of 220 volts;

(1.3) Calibration currents of 5 (30) A, 10 (40) A, 15 (60) A, and 20 (80) A;

(1.4) The constant of the electric meter is indicated on the nameplate;

(1.5) Reference frequency: 50Hz, 60Hz;

(1.6) Accuracy does not require calibration for long-term work;

(1.7) Environmental conditions: Basic operating temperature: -20 ℃ to+55 ℃; Extreme working temperature: -25 ℃ to+60 ℃; relative humidity≤ 85%. (Note): There should be no corrosive gases in the surrounding air to avoid dust, salt spray, condensation, etc.

Reference for price of rail type IoT electricity meter:

1. 5 (30) A: 150 yuan to 220 yuan;

2. 10 (40) A: 220 yuan to 300 yuan;

3. 15 (60) A: 320 yuan to 400 yuan;

4. 20 (80) A: 450 to 550 yuan.

Installation and usage tips for guide rail IoT meters:

(2.1) On the fixed distribution cabinet, choose a suitable location to open an installation hole of the appropriate size.

(2.2) Remove the multifunctional instrument panel, loosen the positioning screw, and remove the fixing clip.

(2.3) Insert the instrument into the instrument hole of the distribution cabinet.

(2.4) Insert the fixing clip of the instrument and fix the positioning screw.

(2.5) Terminal wiring: Please connect the wires correctly according to the instrument housing wiring diagram!

(2.6) Auxiliary power supply: The multifunctional instrument has a universal (AC/DC) switch power input interface. Unless otherwise specified, standard products with 220V (AC/DC) or 110V (AC/DC) power interfaces are provided. The maximum working power supply voltage of the instrument is AC/DC: 80-270V. Please ensure that the power supply provided is suitable for this series of products to prevent product damage.

(2.7) It is recommended to install a 1A fuse on the live side when using an AC power supply. For areas with poor power quality, it is recommended to install surge suppressors and fast pulse suppressors in the power circuit to prevent lightning strikes.

(2.8) Input signal: The multifunctional instrument adopts a calculation method where each measurement channel is separately collected, ensuring complete balance and symmetry during use. It has multiple wiring methods and is suitable for different load forms. (Note): For specific wiring and instrument parameters (pulse constant, etc.), please refer to the wiring diagram provided with the instrument.
