Unfortunately DCDALCIP250-2 are not DALI2 certified
There is no certainty that it will work, because there were no tests for bus power supplies before DALI-2.
DALI devices (switches and sensors) are a big risk. There is a big chance both our switches/sensors and DALI2 devices will clash. The switches/sensors use the extended DALI range but this is not part of DALI2. If DALI2 devices use this same range there could be comms issues.
