LEDGEAR® DALI-2 dimmable linear led drivers

LEDGEAR® isolated SELV DALI linear drivers are ideal for linear systems and stand on: quality of light, reliability and flexibility. These LEDGEAR® L3, L4 and L5 linear drivers are built-in control gear with screw-fixing holes to be settled inside luminaires / fixtures. The output current can be programmed by DALI interface or by selected by DIP switches which allows you to adjust the constant output current to work with different power LED modules. It helps to reduce the inventory and faster to projects.

These LED drivers provide Amplitude Modulation(AM, or CCR) current output, by using these LEDGEAR® LED drivers in your luminaires, you can be sure to offer your customers high quality of light without visual flicker and stroboscopic effects to work in TV studios and security camera environments. Also, this family offers 1-10V dimming as option.

Application: LED linear lights system, troffer, battern lighting, linear track heads, linear bay, and other indoor LED lighting applications
