Controllino with Meanwell 0-10V LED power supply

[Jarda]

Dear Alex,

CONTORLLINO MAXI Automation shall be able to delivery 0-10V on the output (resistor 500 Ohms is internally inside the CONTORLLINO to GND as default. So you shall get the voltage on the output.

Yes, DIM+ shall be connected to AO0 or AO1 and DIM- to GND. Please try to measure the voltage on this pin via Multimeter.

Regards

Jarda

Hello Alex again,

now I’m reading that you are using D15, so you dont have CONTROLLINO Automation and you HAVE MEGA, so you are using PWM control. Sorry for my mistake 😉

Yes, load resistor helps in your case, maybe you can go little bit lower to for example 10K, because current at meanwell power supply is in uA so maybe because of internal capacitance there is still some voltage.

I hope you have version of the power supply for PWM, not for DALI ;-).

Also please note, that PWM input of the meanwell power supply shall be around 10V, so dont use your controllino at 24V 😉

Next point is, that Meanwell power supply needs around 1.5kHz the PWM, it is on the border of possibilities of CONTROLLINO output. So probably output is not able to achive this frequency and on the ouput is “only” the voltage, not PWM. Please check it via oscillocope.

Best Regards
