Hello everyone!
I hate having to ask stupid questions, I'm not an expert in this at all and after quite a bit of research I'm now stuck on a few basic issues.
I'm trying to design and put together a dimming by PWM table lamp with a rotary potentiometer type switch that would dim the light and switch it off. I looked into getting a BuckPuck LED Driver with a 5K potentiometer - https://www.ledsupply.com/led-drivers/buckpuck-dc-led-drivers
However I'm now looking at getting a Mean Well LDD-L (WIired version) Step Down Driver which seems to do the same thing, it's slightly cheaper, smaller and I can get it at my local tech store (pdf attached with driver spec).
My LED spec is 7W / fV 11.0~14.0V / 550mA
So my questions are:
- What power supply do I need for the driver to work with this LED? I'll be using the 500mA driver and I assume the power supply output needs to match the LED input. So would a AC-DC 12v 0.5A power supply work?
- How would I wire up a potentiometer to the driver for the PWM dimming to work? What kind of resistance would the potentiometer need to have? Could the Potentiometer also be used as an on/off function?
Again, sorry for the basic questions or if they've been asked before. I'm new to this.
Thanks in advance for any help!
