The Meanwell LCM-25DA is a constant current LED driver with a built-in DALI interface, designed for lighting designers and installers who need flexible dimming control in a compact footprint. Input and output connections sit on one side of the unit, which makes it straightforward to fit into restricted spaces.

DALI LED driver with multi-stage output

• Dimming control, built-in DALI interface with push dimming, plus 0-10Vdc and PWM signal dimming.
• Output current, multi-stage current output, selectable via built-in DIP switches.
• Input voltage, universal input of 180V to 277VAC with active power factor correction (PFC).
• Dimming curve, logarithmic or linear curve selectable, meeting IEC62386-207.
• Synchronisation, can be synchronised with up to 10 LCM-25D units.
• Protection, short circuit, over voltage and over temperature protection.

Build and certification

The driver is housed in a fully isolated plastic case and is cooled by free air convection, so no fan or heatsink is required. It is a Class II power unit with no functional earth connection, and no-load power consumption stays below 0.5W. Certification covers ENEC EN61347-2-13, EN62384, UL8750 and IEC2386-101 for worldwide use.

Applications

This driver is intended for indoor LED lighting installations where DALI dimming control is required, from architectural fittings to commercial lighting schemes. Part number LCM-25DA. Meanwell backs the unit with a 5 year warranty.
