Lumatek dimming

Hey all,

I have been trying to get a 0-10v analogue signal into the ballast so I can control it via my ESP32's and Home Assistant. With Meanwell drivers its simple, just use a PWM current but I called Lumatek and they said its 0-10v analogue dimming and not PWM...

Well I have an AC Infinity Controller 69 etc as a backup for my AC Infinity fans and things and the AC Controller can Dim the Lumatek lights just fine using the AC Infinity Type A UIS adapter which...is just a USB-C cord to RJ45 with a box in it which does NOTHING! I thought the 'Type A' adapter was a conversion from PWM to Analog 0-10v.

So, what now, is Lumatek telling lies? There are no data sheets on any of their products by the way. Unless the AC Infinity Controller has 0-10v dimming then Lumatek but messing me around saying it doesn't work on PWM.

have you tried feeding the lumatek drivers a pwm signal?.

i gave a mate a couple of my lumatek 600w led's and i have been promising ill get rid of the horible dimmers and get him more control but have never got round to it yet, im sure i read somewhere that they were 0-10v.

Nope, not yet was worried something might happen. Im going to try this afternoon though.

AC infinity fans use 0-10v dimming signal same as the drivers. Depending on the driver it could be pwm dimmable as well.

Use an RC filter to convert your PWM to a DC signal. The mean well drivers do nothing else. They accept both 0-10 V DC or a PWM with 10 V amplitude.
You can also use a PWM with 6 V amplitude to dim from 0-60 %.

What’s a RC filter please? Bought a couple of cheap PWM to 0-10v and was powered by the board at 24v (12v didn’t make the range). One was so so, was about 5-10% off and that could auto turn it off.

Bought a i2c 0-10v 2 channel DAC from DFROBOT and it works perfectly in Arduino IDE and hardly any code, just with 0-5v range or 0-10v range, I set 0-10v. Then the only other command it set voltage (between 0-10) ands it’s perfect down to the .0!

But I have no idea how to how to do anything through MQTT or Arduino IDE hardly. I just use lots of ESPHome and Yaml. If you could covert this into a simple ESPHome Custom Component I will happily send some money via PayPal of something?

Here is Product Page: https://wiki.dfrobot.com/SKU_DFR0971_2_Channel_I2C_0_10V_DAC_Module

An more simple Arduino Git: https://github.com/aaron-neal/GP8403

I even went as far as to get a cheap Zigbee 0-10v dimmer but that was crap, sold the dongle as I have no use for Zigbee really as I use Control4 but might look to see if I can get it to play with Home Assistant.
I then bought a ZWave dimmer and this works perfect but again, I don’t need ZWave and would like to control my other Lumatek 600w light but these are like £40 each and the dongle wasn’t cheap. I would rather pay someone a little to get the above 2 channel coded for simple 0-10v, don’t even need that option in the code.
