(N=driver quantity for synchronized dimming operation
)
Dimming input: Additive resistance
Note : 1. Min. dimming level is about 5% and the output current is not defined when 0%<
I
out<5%.
2. The output current could drop down to 0% when dimming input is about 0k
Ω
or 0Vdc, or 10V PWM signal with 0% duty cycle.

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
Set up for D01-Type in Smart timer dimming software program:
Dimming Level(%)
T1
TIME**
LEVEL**
06:00
100%
T2
07:00
70%
T3
11:00
50%
T4
---
70%
Operating Time(HH:MM)
**: 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.

Operating Time(HH:MM)
**: 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.
