About This Product

■DALI dimming module

BM82D8011-1 is a DALI dimming module that complies with the DALI-2 standard. This module communicates with the host via the DALI bus and converts DALI commands to PWM outputs to feed DALI-enabled LED drivers. The module is designed with a compact package size and can be easily integrated into the LED driver's PCBA. Additionally, by connecting an external resistor to the Iset pin, you can flexibly support constant current drivers that require various output currents.
