The Lijie 400W 24V Ultra-Thin LED Driver Power Supply is a high-power constant voltage LED driver designed for professional lighting systems where stable 24V DC output, compact installation space, and reliable performance are required.

With its long and slim housing design, this 400W LED power supply can be integrated into lighting projects where conventional bulky power supplies may be difficult to install. It provides a maximum output current of 16.7A and is suitable for a wide range of 24V LED lighting applications.

For commercial lighting projects, customized lighting systems, and professional installations, this ultra-thin LED driver provides a practical solution that combines high output power with a space-saving structure.

400W 24V Constant Voltage Output

This LED driver is designed to convert 220–240V AC input power into stable 24V DC output, making it suitable for LED lighting products that require a constant voltage power supply.

Its rated output reaches 400W, with a maximum current of 16.7A, allowing one driver to support relatively high-power LED lighting systems.

Main electrical specifications include:

Actual installation should always be matched with the total connected lighting load and local electrical requirements.

Ultra-Thin Design for Space-Saving Installation

One of the main advantages of this 400W LED driver is its ultra-thin housing design.

Compared with many conventional high-power LED power supplies, the slim structure helps reduce installation space and makes the driver easier to integrate into lighting systems with limited mounting space.

This design can be especially useful for:

Commercial lighting systems
Linear lighting installations
Architectural lighting
Display and retail lighting
Cabinet and furniture lighting systems
Custom lighting projects
24V LED strip lighting
Engineering lighting applications

For professional installers and lighting manufacturers, a slimmer driver can also make internal wiring and system layout more flexible.

Stable 24V Power for Professional LED Lighting

Stable power output is important for the long-term operation of LED lighting systems.

The Lijie 400W LED driver provides constant 24V DC output for compatible lighting products. A properly selected constant voltage driver helps maintain consistent power delivery to the connected LED load.

When selecting a driver, the total LED load should normally remain below the maximum rated power of the power supply. Leaving appropriate power margin can help provide more reliable operation in real-world installations.

For example, a lighting system with a total load close to 400W should be evaluated carefully according to installation temperature, operating time, ventilation conditions, and project requirements.

High Power Factor for Lighting Applications

The driver is designed with a power factor of up to 0.95, helping improve electrical efficiency in professional lighting installations.

A higher power factor is particularly useful in commercial and engineering projects where multiple LED drivers may be installed within the same lighting system.

This makes the 400W power supply suitable for projects that require both high output power and professional electrical performance.

Clear Input and Output Terminal Design

The LED driver uses clearly separated INPUT and OUTPUT terminals.

The input side is designed for AC power connection, while the output side provides the DC connection required for the LED lighting system.

The clearly identified terminals make wiring easier for installers and help reduce connection errors during assembly and installation.

For safety reasons, installation should be completed by qualified personnel according to the wiring markings on the product and applicable local electrical standards.

Designed for Commercial and Engineering Lighting

This 400W 24V LED driver is particularly suitable for applications where a large amount of 24V LED lighting needs to be powered from a single driver.

Typical applications include:

Commercial Lighting

Suitable for retail stores, showrooms, shopping spaces, offices, hotels, restaurants, and other commercial lighting environments.

Linear LED Lighting

The 24V constant voltage output makes the power supply suitable for many LED strip and linear lighting systems.

Architectural Lighting

It can be integrated into architectural lighting projects where compact power supply installation and high output power are required.

Customized Lighting Systems

For lighting manufacturers and project contractors, the ultra-thin format provides greater flexibility when integrating the driver into customized lighting products.

Why Choose an Ultra-Thin 400W LED Driver?

The key advantages of this model include:

• 400W high-power output
• Stable DC 24V constant voltage
• Maximum 16.7A output current
• Ultra-thin housing design
• PF 0.95 power factor
• Clearly marked input and output terminals
• SELV marked design
• Suitable for commercial and engineering lighting
• Designed for professional LED lighting systems

How to Select the Correct 24V LED Driver

Choosing the right LED power supply is important for both system reliability and lighting performance.

Before selecting this 400W model, confirm the following information:

LED operating voltage:
The connected lighting system should be designed for 24V DC constant voltage input.

Total LED power:
Calculate the combined wattage of all connected LED products.

Installation environment:
Consider ventilation, ambient temperature, available mounting space, and operating time.

Wiring requirements:
Use suitable cable sizes and follow the input/output markings on the driver.

Safety requirements:
Installation should comply with local electrical regulations and project specifications.

If the lighting system requires a different power level or output specification, another LED driver model may be more suitable.
