I need NO! PWM circuit board at all mode

shrike2222 · Sep 7, 2012

Hello.

I have found for NO PWM led driver. I had two NAN-JG led drivers but those are using mode switching by PWM circuit.

At High mode, there is no noise, but at medium and low mode I can hear noise or sound. That is getting on my nervous at the room.

So, I need to NO! PWM led driver. Is there anyone who know this?

thanks.

Have you tried Taskled drivers?

thanks, but I need a driver 17mm diameter.

check intl-outdoor and cn qualitygoods.
they LABELED some of their drivers as Constant current

Try a resistor. No pwm, no noise, no RFI, highly reliable. Not perfect, but it works.

I have long used this kind of drivers for a long time... Do I have a hear problem?

thanks derfyled. I already found that circuit. But, the max current is not enough to my demand.

dear Changchung. Where did you find it?
