3、 Core features of the product

1. Characteristics of intelligent lighting control module

Functional integration: integrating time control, light control, human body sensing, fire control, BA dry contact, remote control, and manual control into one

Independent working ability: Comes with a clock and display screen, can work offline, and independently sets parameters

Communication compatibility: equipped with RS485 communication interface, supports MODBUS protocol, can connect to third-party upper system

Scene control: With the panel, multiple scene modes can be controlled, and with the gateway, remote management can be achieved

2. Advantages of latitude and longitude time controllers (astronomical clocks)

Multi channel output: A single unit has 8 independent outputs, which can be configured with 2/4/6/8 channels, each with a rated current of 5A (pure resistance type)

Persistent timing: using imported built-in battery clock chip, it can time normally for 10 years without external power supply, reducing maintenance

Precise control: Automatically calculate sunrise and sunset times based on latitude and longitude, without manual adjustment, adapting to seasonal changes

Clear Display: Equipped with a 19264 LCD screen, the user interface is user-friendly

3. Core technology of energy-saving control device

Electromagnetic voltage regulation technology: using electromagnetic transformers to stabilize voltage, output without harmonics, complete waveform without distortion, and avoid harmonic pollution caused by thyristor voltage regulation

Three phase independent regulation: supports independent three-phase adjustment, with voltage imbalance below 1%, suitable for different loads

Fault self handling: automatic bypass after alarm, seamless switching, ensuring continuous operation

Comprehensive protection: equipped with full protection against overload, overheating, overvoltage, undervoltage, and short circuit

4. Features of remote monitoring system

Multi protocol support: compatible with various protocols such as CAN, 485-MODBUS, MQTT, OPC, API, TCP, etc

Flexible control mode: supports single light control (any single light switch and brightness adjustment) and group control (batch operation)

Accurate timing: The concentrator supports remote manual and automatic timing, and can be equipped with a GPS positioning timing module, accurate to the millisecond level

Data collection: Real time monitoring of parameters such as current, voltage, power, and power factor to achieve energy consumption analysis

5. Advantages of Distribution Box Products

High protection level: using PU foam sealing strip, with a protection level of IP56, suitable for harsh outdoor environments

High quality material: 304 stainless steel material, surface brushed treatment, with double toothed lock core stainless steel lock system

Structural optimization: multi-layer protective grooves at the box mouth to prevent dirt and water from entering; Galvanized mounting plates can be wired outside the box

Intelligent integration: Built in intelligent control module, realizing remote monitoring and energy-saving control integration

6. Characteristics of the overall solution
