LED Dimming Power Supply [Copy link]

Is there anyone who is good at LED power supply? ? This is my first time to use LED lamps. Can anyone tell me about the isolated dimming signal and non-isolated dimming signal in 1-10V dimming signal? ? Are there any special regulations that require the use of isolated dimming signal? ?

There are no specific regulations. Isolation or not is entirely up to your needs.

Isolate or not, there is no specific law requiring you to do so

The question is, what occasions do your lights go for your customers? If they require safety certification, then they just need to meet the safety certification requirements.

For domestic use, 3C certification is required

Exporting to Europe requires CE certification, and exporting to the United States requires UL certification

Let's talk about the 1-10V dimming mentioned by the original poster. It is very different from 0-10V dimming. The technical difference is particularly large, because 1-10V dimming can only dim, but cannot be turned off, because there is still a dimming signal and voltage. I don't know what form the original poster's control method is. Generally speaking, 0-10V dimming is achieved by digital PWM dimming.
Isolation or not should be considered from the perspective of safe use.

This is the first time we enter the LED lighting industry. We now have a product that needs Bluetooth control (we made this control board ourselves), which outputs a 0-10V dimming signal. The power supply is outsourced. Last time we talked about this 0-10V dimming signal, there are two solutions, one is isolated and the other is non-isolated. Because of the size, they said they would do non-isolated. The front end has done low-voltage DC-DC solutions, and it doesn’t matter whether the 0-10V signal is isolated or not. I don’t know when to choose isolation and when to choose non-isolation for this kind of AC-DC 0-10V signal.
