LED driver MEAN WELL ELG-240-48-3Y 240W IP20 100-305V 5A 48V

The MEAN WELL ELG-240-48-3Y is a single-output LED driver delivering up to 240 W with a fixed constant-current output of 5 A at 48 VDC. Designed for indoor lighting installations, it accepts an AC input voltage range of 100–305 VAC and includes power factor correction (PFC). The unit has an IP20 enclosure and three-wire AC input, with a cable-type DC output for connection to LED loads. Compact dimensions (71 mm × 244 mm × 37.5 mm) facilitate integration into fixtures and control cabinets.

Advantages

The ELG-240-48-3Y offers a stable 48 VDC output with a fixed 5 A current, supporting constant-voltage plus constant-current (CV+CC) operation suitable for many LED applications. Wide input range (100–305 VAC) allows use across different mains supplies while built-in PFC improves power quality. Its compact form factor and cable output simplify installation in indoor lighting systems.

Suitable for

• Indoor LED luminaires and panels
• Commercial and retail lighting
