Since we have many customer from America and Europe customers give us feedback that want the 12V triac dimming led power supply with high output PWM frequency, hence after our engineers trying, we have completed this designed.

Just keeping you posted that we have improved the output PWM frequency for UL triac dimmable led driver and non-dimmable led power supply from 800HZ to be 20000HZ successfully, so they are now totally flicker free, trust this will be a strong competitive factor to beat drivers from others.  we will provide this version to all of your future following orders.

Please note that this high PWM output frequency 20000HZ is for UL drivers that to said our ETL version led power supply is not to be improved to high PWM output frequency, only 800Hz. So we may suggest customers purchase our UL high quality led drivers.
