Round Shape dali-2 dimmable 15w constant voltage led drivers 12v 24V for led strip lights
This compact DALI-2 intelligent constant-voltage LED driver features short-circuit, over-temperature, and overload protection functions. Housed in a plastic casing designed for efficient heat dissipation, its small form factor makes it ideal for installation in LED lighting projects within confined indoor spaces.
