ELG-300 LED Driver Overview
The ELG-300 LED Driver from MEAN WELL is a high-power AC/DC power solution designed for professional LED lighting installations. The ELG-300-24A model provides a regulated 24V DC output, up to 12.5A rated current and a maximum rated output of 300W under the specified input conditions.
Its combined constant-voltage and constant-current operating design allows the driver to support compatible LED strips, modules and high-output luminaires. A wide 100–305V AC input range makes it suitable for projects using different electrical networks, while derating may be required at lower input voltages.
Efficient 24V Power Supply
The ELG-300-24A reaches up to 94% typical efficiency, helping reduce electrical losses and unnecessary heat during continuous operation. Its fanless construction uses natural air convection, providing quiet performance without mechanical cooling components.
The driver also includes active power-factor correction and built-in protection against short circuit, overcurrent, overvoltage and excessive operating temperature. These functions support dependable operation when the unit is correctly selected, installed and matched to the connected LED load.
Durable IP67 Metal Enclosure
The robust metal housing and IP67 protection rating make the driver suitable for indoor and outdoor lighting environments exposed to dust or moisture. Its sealed enclosure is suitable for professional architectural, commercial and industrial projects where durability is essential.
The built-in potentiometers allow the installer to adjust output voltage and output current within the permitted ranges. This provides additional flexibility when commissioning compatible LED systems.
Recommended Lighting Applications
The ELG-300 LED Driver is suitable for applications including:
- LED bay lighting
- LED floodlights
- Architectural façade lighting
- High-output LED strip lighting
- Stage lighting
- Landscape illumination
- Commercial signage
- Industrial lighting
- Area and infrastructure lighting
- Compatible DMX-controlled lighting systems
Its high output capacity can reduce the number of separate power supplies required in large lighting installations, provided that cable sizes, voltage drop and load distribution are properly calculated.

The official specification states that full available output depends on the input voltage and operating conditions. Load derating must therefore be considered during system design.
Professional Installation
The driver should be installed in a suitable location with enough space for heat dissipation. Input, output, grounding and adjustment procedures must follow the product label and the manufacturer’s instructions
