LED driver MEAN WELL ELG-100-24DA-3Y 100W IP20 100-305V 4A 24V

The MEAN WELL ELG-100-24DA-3Y is an AC-DC single-output LED driver providing 24V DC at 4A and up to 100W output power. It accepts a wide AC input range of 100–305V and integrates both constant-current and constant-voltage (CC+CV) regulation with PFC for stable performance. The unit features DALI dimming control and a three‑wire input configuration, and its IP20 rating makes it intended for indoor installations.

Advantages

The ELG-100-24DA-3Y combines CC+CV regulation and active power factor correction to deliver consistent light output and improved mains compatibility. Built-in DALI control enables digital dimming and system integration. Designed for straightforward installation, the driver provides a fixed 24V output at a rated current of 4A and a maximum power of 100W.

Suitable for

• Indoor LED strips and modules requiring 24V supply
• Commercial and office lighting with DALI dimming
• Retrofit drivers for constant-voltage LED fixtures

How to use

Connect the driver to the AC mains (100–305V) using the three‑wire input following local electrical codes. Wire the 24V DC output to the LED load ensuring polarity and that the total connected load does not exceed 4A (100W). Integrate the DALI control wiring according to the DALI system requirements for dimming operation. Install the unit in a dry, indoor location compatible with IP20 protection.

Recommendations

For reliable operation, confirm LED load compatibility with a 24V constant-voltage driver and keep ambient temperature within the manufacturer's specified range. Ensure DALI wiring and power connections are performed by qualified personnel.
