DALI Step-Down LED Driver DC to DC Constant Current
LDD-H-DA
The MEAN WELL LDD-H-DA series step-down DC to DC LED drivers have a fully encapsulated IP67 enclosure to prevent moisture and dust ingress. All models can be dimmed by a DALI controller.
There are two form factors to choose from: PCB mount or wire terminations.
These LED drivers take a DC voltage input from sources, such as 12V or 24V solar panels or batteries and convert it into a constant current output that is suitable for powering most LEDs.
See table below for models in the range.

Disclaimer
Due to demonstrated incompatibilities between some DALI systems, it is strongly recommended that all DALI products are tested with intended equipment before installation. DALI drivers which are incompatible with untested applications will not be accepted back as warranty claims if they are not tested as being faulty.
