The DALI bus is said to be 0V to 16V nominal
However, the “High” voltage can be anywhere from 9V5 to 22V5.
Is this really so? Is it seriously that poor in tolerance?
It makes designing a opto based DALI receiver so much more problematic in terms of needing optocouplers and associated circuitry which can manage the wide range of currents that one gets due to this wide bus range.
What percentage of DALI PSU’s give a voltage outside 16+/-1V for the DALI bus?
