I designed a controller arduino based. No harm works great.lol I've been search the internet high-and-low trying to hook up the meanwell 3-1 dimming to a raspberry pi.... and I somehow end up at thc farmer.
So this doesn't damage the arduino at all? I saw some vague reference that you might end up with issues because the dimmer circuit ground and the arduino ground aren't guaranteed to be common. I was going to try this out with an octocoupler, but the NPN route was the first one i was thinking.
Iv been wondering what else I need besides the relay to dim off the meanwell hlg with a potentiometer. The meanwell driver only puts out .1 ma for the dimming signal. the relays that have been recommended require a minimum of 3 ma to trigger it. the microcontrollers with there own power supply put out 10-40 ma which is enough. iv been looking at this pigtail relay from sparkfun or the beefcake relay. can you provide me any insight on how to dim off a meanwell hlg driver with a potentiometer and these relays ?I participate at other sites and I love tinkering with electronics. I have been following a discussion on 3 in 1 Dimming capabilities and what it is useful for.
For me, I found out how to use an arduino device; Storm, Typhon, or arduino uno; to dim led fixtures identical to the ones we DIY here with meanwell HLG series of dimmable drivers.
The article talks about many features, but there is an entire article elsewhere about not only dimming but also turning on/off HLG series of drivers already available in Europe, but not in the USA.
The figure at the bottom shows an on/off device. The device is available in two formats, hobby build or assembled. The hobby version can be found by searching for controllable power outlet on sparkfunhttps://www.sparkfun.com/products/11042 or by looking for the same at yourduino http://yourduino.com/sunshop2/index.php?l=product_detail&p=218.
I bought the kit and assembled it and tested it today with my coralux storm controller and it works. Next I will build a duplex outlet box with two power controllers on the outside to control turning lights on/off, dim, and dim Far Red, Deep Red, IR, and Royal Blue, all controlled from one console for two rooms. The unit uses a 5v dc signal from any arduino device.
I hope this helps others and they can learn from this, as well
peace

Using a beefcake works well an even easier is to get the adafruit 4 outlet receptacle with pwm control. All you have to do ia run your pwm and gnd to the outlet plug in your fixture and done room to plug in two fixtures in factIv been wondering what else I need besides the relay to dim off the meanwell hlg with a potentiometer.

For dimming you need a 5v to 10v pwm converter board with a separate 10v power supply connected between the controller and the driver.Iv been wondering what else I need besides the relay to dim off the meanwell hlg with a potentiometer.

yah I know that much but the problem I face is that I dont have a pwm controller (which requires its own power supply) all I have is a potentiometer, the mean well hlg puts out its own voltage and dimms based on what it gets back but the current is only 0.1 mA from what I read on the relays they have a minimum voltage and current that is needed to trigger it the current needed as far higher then .1 mAFor dimming you need a 5v to 10v pwm converter board with a separate 10v power supply connected between the controller and the driver.
