Happy New Year colleagues!

We use some chinese PWM dimmers (Ltech) almost on each power supplies.
The UL guy say what they not listed and we can not use them.
But I think this is Class 2 device and it's not suppose to be listed.
What dimmers you using, anybody can recommend UL listed PWM dimmers?
Thanks.

sorry my English
