DALI BUS POWER
The DALI bus is a shared Power and DALI bus. A minimum of 14 volts is recommended for operation, with up to 260 mA allowed. Operation at lower currents is recommended, as long as the voltage does not fall below 14 volts.
DALI Devices can be powered by the bus up to 4 mA each - most devices need less than 2 ma. This allows shared power and data on 2 wires. Some DALI masters provide power, others do not. Here is a list of Power supply options we have tested.

* means that multiple DALI power supplies can be wired in parallel, up to 260 mA total
DALI bus devices that provide power can be wired in parallel up to 260 mA total. if the RELV4-16 is used - disable power in the ATX LED product in the list above.
Hardware Version Notes
- AL-WS-DR2 V1 and V2 can only drive 140 mA
- AL-WS-010v needs 6 mA to operate
- AL-DALI-8B multiswitch needs 3 mA + 1 mA per LED active
- AL-DALI-HAT-2I and 4I have no power supply built in
