Notes:

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

2. The dimmer can also be replaced by an active 0-10V voltage source signal or passive components like

zener.

3. When 0-10V negative logic dimming mode and Dim+ is open, the driver will dim to off and be standby.

 PWM Dimming

 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.
