PLC Data Concentrator Unit
Smart Concentrator Gateway with PLC-IoT Communication
Smart Concentrator Gateway adopts the latest generation of PLC-IoT (Power Line Communication + Internet of Things) technology, enabling seamless data transmission through existing power lines. It works with single light controllers or PLC smart drive power supplies as a central communication hub that connects devices to cloud-based big data platforms.
The MG-E3 supports communication management, data transmission, protocol conversion, and data processing, empowering users to remotely monitor, analyze, and control electrical equipment anytime, anywhere.
Complying with the State Grid concentrator standard, this gateway delivers exceptional electromagnetic compatibility (EMC) and resists interference from high-voltage spikes, magnetic fields, static electricity, and lightning surges.
Built for durability, the MG-E3 features a sealed ABS enclosure that is both waterproof and flame-retardant, along with a lightweight, wall-mounted design for easy installation and long-term reliability in demanding industrial and outdoor environments.
Ideal for street lighting, smart city infrastructure, industrial energy systems, and IoT communication networks, the MG-E3 ensures stable connectivity, high safety, and intelligent data management.

Note: The concentrator supports three-phase electricity, Ua—A phase electricity, Ub—B phase electricity, Uc—C phase electricity, and Un—neutral line. (For single-phase electricity, it is recommended to connect the live wire to Ub and the neutral wire to Un).
Note: Do not connect 'L' (live wire) and 'N' (neutral wire) incorrectly to avoid affecting the normal operation.
Installation Instructions
Install and fix the terminal in the power distribution cabinet, determine the terminal operating voltage, current, and wiring method according to the terminal type (see the label on the front panel), and connect the wiring of each voltage and current terminal. Open the front panel of the terminal, insert the SIM card with the GPRS service function activated, and insert the rechargeable battery attached to the terminal. After checking the wiring, power on and run.
Operation Button Description
This terminal uses six-button operation. Users can use the USB interface and buttons to configure the gateway and query gateway information. For specific operations, please refer to the "Micronature Inwu Cloud Platform User Manual". The button description is shown in Figure 6.
