SPECIFICATION
Block Diagram
DRIVING METHODS OF LED MODULE
- This series is able to work in either Constant Current mode (a direct drive way) or Constant Voltage mode (usually through additional DC/DC driver) to drive the LEDs.
- Typical output current normalized by rated current (%)
DIMMING OPERATION
-
3 in 1 dimming function (for B/AB-Type)
-
Output constant current level can be adjusted by applying one of the three methodologies between DIM+ and DIM-:
0 ~ 10VDC, or 10V PWM signal or resistance. -
Direct connecting to LEDs is suggested. It is not suitable ‧ to be used with additional drivers.
-
Dimming source current from power supply: 100μA (typ.)
-
Applying additive 0 ~ 10VDC
-
Applying additive 10V PWM signal (frequency range 100Hz ~ 3KHz):
-
Applying additive resistance:
Note :
- Min. dimming level is about 5% and the output current is not defined when 0%< Iout<5%
- The output current could drop down to 0% when dimming input is about 0kΩ 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:
- 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:
- The power supply will switch to the constant current level at 100% starting from 6:00pm.
- 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
- 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
- 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 The constant current level remains till 8:00am, which is 14:00 after the power supply turns on.
- Ex: ◎ D02-Type: the profile recommended for street lighting
- 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:
- The power supply will switch to the constant current level at 50% starting from 5:00pm.
- 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
- 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
- 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
- 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 The constant current level remains till 6:30am, which is 14:00 after the power supply turns on.
- Ex: ◎ D03-Type: the profile recommended for tunnel lighting
Set up for D03-Type in Smart timer dimming software
program:
- TIME matches Operating Time in the diagram whereas LEVEL matches Dimming Level.
Example: If a tunnel lighting application adopts D03-Type, when turning on the power supply at 4:30pm, for instance:
- The power supply will switch to the constant current level at 70% starting from 4:30pm.
- The power supply will switch to the constant current level at 100% in turn, starting from 6:00pm, which is 01:30 after the power supply turns
- 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 The constant current level remains till 6:30am, which is 14:00 after the power supply turns on.
