Implementation 6

: Negative logic

Notes:

1.

Do NOT connect Dim− to the output V− or V+, otherwise the driver will not work properly.

2.

When 10V PWM negative logic dimming mode and Dim+ is open, the driver will output maximum current.

 Dim/CCT Time Dimming

Time dimming control includes 3 kinds of modes, they are Self Adapting-Midnight, Self Adapting-

Percentage and Traditional Timer.



Self Adapting-Midnight: Automatically adjusts the dimming curve based on the on-time of past two

days (if difference <15 minutes), assuming that the center point of the dimming curve is midnight local

time.



Self Adapting-Percentage: Automatically adjusts the on-time of each step by a constant percentage =

(actual on-time for the past 2 days if difference <15 min) / (programmed on-time from the dimming

curve).



Traditional Timer: Follows the programmed timing curve after power on with no changes.

 Output Lumen Compensation

Output Lumen Compensation (OLC) may be used to maintain constant light output over the life of the LEDs

by driving them at a reduced current when new, then gradually increasing the drive current over time to

counteract LED lumen degradation.
