2 Channel I2C 0-10V DAC Module (SKU_DFR097)

Hey all,

Im trying to adjust my LED driver unit using its DIM - ad + connections. The drivers is not like the Meanwell with PWM but analog 0-10v input to the driver for changing the main output from the driver to LED's.

I do have a cheap eBay device which does the same job as this but includes a 10-30v external input so it can provide a true 0-10v. I wanted to know how does this give a full 10v output to the driver when the Arduino only gives out a max of 3.3 or 5v? 

My LED driver doesnt give out a 10v output, its a constant/current output but is dimmed using a 2 wire dimmer with manual 0%-25%-50%-75%-100% pot or it can be hooked up to a controller which gives out 0-10v and has 0.1 increments depending on the input from this.

If it does work ok without external input of 12-30v or similar then do you happen to have a 4 channel version for 4 LED drivers or would I need to use two of these? 

Many thanks.
