DALI dimming signal distortion correction device DALI lighting control

DALI dimming signal distortion correction device DALI lighting control

Using this DALI product on some DALI line dimming signal lines improves the reliability of DALI communication.

Depending on the thickness of the DALI signal wiring and the branching of the star wiring, distortion of the DALI dimming signal may occur. Furthermore, the tolerance for signal distortion may vary among DALI devices on the line, which can lead to a decrease in communication quality. DALI dimming signal distortion correction devices help to correct this distortion of the DALI dimming signal and improve the reliability of DALI communication.
