Dimmable constant current LED driver with strain-relief that is a part of the 4 Generation of LED drivers which creates new luminaire design options. The large operating window and NFC interface offer greater flexibility and simplify logistics.
This LED driver with a second SELV DALI power supply is the perfect solution for small room group applications and luminaires with sensor integration on LED modules. With DALI-2 / D4i specifications for the storage and transmission of essential data across the SELV barrier. This enables sensor integration on space critical designs and lays the foundations for future-proof solutions with simple facility management, energy control and much more.
