LED driver MEAN WELL ELG-100-48DA-3Y Output power 100 W IP20

The MEAN WELL ELG-100-48DA-3Y is an AC‑DC single‑output LED driver combining constant current and constant voltage (CC+CV) operation with active power factor correction (PFC). It delivers 48 V DC at up to 2 A (100 W) from a wide AC input of 100–305 V and features three‑wire input and cable output. The compact housing (63 × 199 × 35.5 mm) and IP20 enclosure make it suitable for indoor lighting installations that require DALI dimming control.

Advantages

The ELG-100-48DA-3Y provides stable output with both CC and CV modes to protect LEDs and connected loads. Integrated PFC improves mains compatibility and reduces input distortion. Built‑in DALI dimming control allows digital brightness adjustment and easy integration into DALI lighting systems. Its compact footprint facilitates installation in confined spaces.

Suitable for

• Indoor LED fixtures and luminaires
• Architectural and commercial lighting with DALI control
• Retrofit projects requiring a 48 V DC LED supply
