LED driver mean well ELG-100-24-3Y, 100W, 24V DC, 4A, AC 100–305V, IP20, 63×199×35.5 mm

Mean Well ELG-100-24-3Y is a compact 100 W LED driver delivering a 24 V DC constant-voltage output with a rated current of 4 A. It operates from a wide AC input range of 100–305 V and provides stable power for indoor LED lighting, signage and retrofit installations. The unit's IP20 protection rating and small dimensions (63×199×35.5 mm) make it suitable for fixtures and enclosed housings where a reliable 24 V supply is required.

Advantages

The ELG-100-24-3Y offers both constant-current and constant-voltage control features with power factor correction (PFC) to improve mains compatibility. Its compact size simplifies integration into luminaires and sign cabinets, while the fixed 24 V output and 4 A rating deliver predictable performance for LED arrays. The wide input voltage range ensures operation across different mains systems, and the robust design reduces flicker and maintenance requirements.

Suitable for

• Indoor LED fixtures and panel lighting
• Channel signs and illuminated advertising
• Retrofit conversions requiring a stable 24 V supply
• Enclosed or recessed installations with IP20-rated components

How to use

Install the ELG-100-24-3Y inside a compatible fixture or enclosure ensuring adequate ventilation and adherence to IP20 constraints. Connect the AC mains to the three-wire input following local wiring regulations, then connect the 24 V DC output to the LED module or driver input. Verify correct polarity and secure all cable entries to prevent strain on the terminals. Test the installation at low load before full operation.

Recommendations

Use the driver in dry, indoor environments consistent with its IP20 rating. Avoid exposure to moisture or outdoor installation unless additional environmental protection is provided. Ensure the load does not exceed 4 A and allow for ventilation around the unit to maintain temperature within the manufacturer's limits.
