※ DAL I Interface (primary side; for DA-Type) ‧ Apply DALI signal between DA+ and DA- . ‧ DAL I protocol comprises 16 groups and 64 addresses. ‧ First step is fixed at 8% of output. ※ Smart timer dimming function (for Dxx-Type by User definition) MEAN WELL Smart timer dimming primarily provides the adaptive proportion dimming profile for the output constant current level to perform up to 14 consecutive hours. 3 dimming profiles hereunder are defined accounting for the most frequently seen applications. If other options may be needed, please contact MEAN WELL for details. Ex : ◎ D01-Type: the profile recommended for residential lighting Ex: ◎ D02-Type: the profile recommended for street lighting **: TIME matches Operating Time in the diagram whereas LEVEL matches Dimming Level. Example: If a residential lighting application adopts D01-Type, when turning on the power supply at 6:00pm, for instance: [1] The power supply will switch to the constant current level at 100% starting from 6:00pm. [2] The power supply will switch to the constant current level at 70% in turn, starting from 0:00am, which is 06:00 after the power supply turns on. [3] The power supply will switch to the constant current level at 50% in turn, starting from 1:00am, which is 07:00 after the power supply turns on. [4] The power supply will switch to the constant current level at 70% in turn, starting from 5:00am, which is 11:00 after the power supply turns on. The constant current level remains till 8:00am, which is 14:00 after the power supply turns on. **: TIME matches Operating Time in the diagram whereas LEVEL matches Dimming Level. Example: If a street lighting application adopts D02-Type, when turning on the power supply at 5:00pm, for instance: [1] The power supply will switch to the constant current level at 50% starting from 5:00pm. [2] The power supply will switch to the constant current level at 80% in turn, starting from 6:00pm, which is 01:00 after the power supply turns on. [3] The power supply will switch to the constant current level at 100% in turn, starting from 8:00pm, which is 03:00 after the power supply turns on. [4] The power supply will switch to the constant current level at 60% in turn, starting from 1:00am, which is 08:00 after the power supply turns on. [5] The power supply will switch to the constant current level at 80% in turn, starting from 4:00am, which is 11:00 after the power supply turns on. The constant current level remains till 6:30am, which is 14:00 after the power supply turns on.
