: Negative logic

Notes:

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

2. When PWM negative logic dimming mode and Dim+ is open, the driver will dim to off and be standby.

 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.

 Minimum Dimming Level with 5% or 10% Selectable

The minimum dimming level can be set as 5% or 10% by Inventronics Multi Programmer,10% is default.

 Maximum Dimming Level with 9V or 10V Selectable

The maximum dimming level can be set as corresponding dimming voltage is 9V or 10V by Inventronics

Multi Programmer,9V is default.

 Fade Time Adjustable

Soft-start time and dimming slope can be adjusted by Inventronics Multi Programmer to get customized

fade time experience, disable mode is default.

 End Of Life

End-of-Life (EOL) is providing a visual notification to a user that the LED module has reached the end of

manufacturer-specified life and that the replacement is recommended. Once active, an indication is given at

each power-up of the driver, which the driver indicates this through a lower light output during the first 1

minute before normal operation is continued.

 Digital Dimming

Inventronics Digital Dimming is a UART (Universal Asynchronous Receive Transmitter) based

communication protocol. Please refer to Inventronics Digital Dimming file for details.
