MEAN WELL ELG-300-24A LED driver 300W IP20 100-305V 24V

The MEAN WELL ELG-300-24A is an AC-DC single-output LED driver delivering up to 300 W with a nominal output of 24 V DC at 12.5 A. It supports constant voltage and constant current (CV+CC) operation and includes power factor correction (PFC). The unit accepts a wide AC input range of 100–305 V and has compact dimensions (77 mm × 246 mm × 39.5 mm) suitable for many lighting installations.

Advantages

This LED driver provides stable 24 V output with up to 12.5 A current, combined CV and CC control, and integrated PFC to improve mains performance. The device features adjustable output current and voltage via a built-in potentiometer for fine tuning. Its compact form factor allows installation in confined spaces common in commercial and architectural lighting.

Suitable for

• LED strips and modules requiring 24 V DC supply
• Interior and fixture-mounted commercial lighting
• Architectural and accent lighting installations
• Retrofit projects where a compact 300 W driver is needed

How to use

Install the ELG-300-24A according to local electrical codes and the manufacturer’s installation instructions. Connect the AC input (100–305 V) to the driver input terminals and the 24 V DC output to the LED load, observing polarity. Use the built-in potentiometer to adjust output current (Io) or fine-tune output voltage (Vo) as required for the connected LED system. Ensure adequate ventilation and secure mounting to avoid overheating.

Recommendations

For reliable operation, match the LED load to the driver’s 24 V / 12.5 A rating without exceeding the 300 W maximum. Provide proper cooling and follow wiring and grounding best practices. Prefer installation by a qualified electrician and consult Mean Well documentation for protection, dimming options, and safety limits.
