Dimmer switch inconsistently working

[shtam]

Hi all, I recently replaced a BG dimmer that had failed (wouldn't click) with this module, connecting to some LED strips:

SS-EN-00-PDM400 Enkin 400W LED Intelligent Universal Dimmer - Enkin

enkin.com

Weirdly, it does work, but inconsistently - like 1 in 10 times it will turn on and the dimming works as expected, but even when it does work there's a ~3 second delay. I've tried it on both trailing edge and leading edge but same problem.

Is there anything obvious I should try, or is this dimmer just incompatible with my lights? I've got a similar module (lower wattage) in another room with standard LED spotlights and it works but also has the annoying ~3 second delay. They're relatively expensive dimmers so I'm a bit surprised (and annoyed ).

Very much an amateur so please let me know if there's any further info I can provide. Thank you!

It says in the spec it has a soft start, so doing it seems what it should do.

3 second delay is a very soft start but ok, I can just about live with that.

What about the other issue where it inconsistently turns on the LED strips altogether? Is that the soft start confusing the transformers?

Is that the soft start confusing the transformers?

Possibly, some LED drivers require a certain amount of current to start operating.
However if started at full brightness they should work reliably all the time.

Thanks for the response - unfortunately it doesn't work reliably even when at full brightness

Try a normal on/off switch temporarily - if that works, then it's 100% some problem with the dimmer.
If it's still unreliable then the LED driver is faulty.
