Dimming DIY LEDs start flashing at 24%

[Jyetman]

I have a DIY project with a LED pad from a maxspect razor and from a previous thread had help on what type of PS was needed.

So now that its all hooked up I got another problem.

I'm using a mean well LPF-25D-12 12V 2.1A 25.2W Single Output Switching with PFC LED Power Supply. It successfully connected to a PWM Interface Board which is interfaced to my APEX V1/V2 ports. All is working however it only dims from 100% down to 24% which is still too bright. Any lower then 24% the LEDS flash. Is there anything I can do to bring it down further near 0%? I was thinking a small 12V cap not sure what size or if that would even work any thoughts?

AFAICT the driver can do 1-10V analog.. Why the conversion board?

Secondly driver only dims to 10% ..then may jump to off or flash..
Usually people set Apex to 10% or greater and then shut off the driver w/ AC relay module..
(not an Apex guy)

to get 0-100% dimming requires different drivers..and possibly ps..
