Answer: Yes, there are three series of triac dimming led driver from Smarts, they are called as version 1.0, version 2.0 and version 3. Here is the general informations as below.

Version 1.0 don’t have PWM output function. This series is the early type led driver which we developed around 2015. They are 3 year warranty and 12vdc 24vdc led driver design output, 100-130vac or 170-265vac.

As the time going, our version 2 with 300Hz frequency was released in the market soon, they did have PWM output with 300H output.5 years warranty, 100-130vac or 170-265vac.

Nowadays, we have developed version 3.0  have PWM output with 800Hz frequency. They are 7 yeasr warranty with 100-277vac.

Anyway, we are focusiong on inceasing more and more led strip driver to cater to the big demand of the market. So we will try to make the subsequent operation will increase the operating frequency to 4000HZ~20000HZ to control the strobe problem but still be debugging.
