I know this is a few months old but I wanted to toss out a word of caution to anyone considering controlling the Mean Well LDD series drivers with an Arduino for use over a saltwater reef aquarium.

The basic connection scheme for this drivers is very easy.

Possibly temp probe and adjusting 12v fan speed mm case fan etc based on it. Add to basket Add to wish list.

The PWM Pulse Width Modulation signal generator is an electronic circuit which provides an electrical signal as a square wave.

The driver ensures a constant current through the series of LEDs blue circuit. This can be all done in code with no way to change, as long as I can set clock at least to proper values, not sure how that is done on Arduino and if possible through just usb connection.

For examplein the proposed scheme, the led string has five LEDs ; s upposing you are running them at mA and them having a voltage drop of 3V eachthe total voltage of the string will be 15V 3V x 5 LEDs. I will be using it to run some cooling fans, but would be nice to throw Ld on it as well. It always takes longer than you expect, even when you take into account Hofstadter’s Law.

More information can be found in our menawell policy. So I guess the first question would be, do I just connect ground pin on Arduino to the ground on the LED power source? My reading of the datasheet is that it has a PWM dimming input which accepts voltage levels and frequencies that are just fine for an Arduino PWM output.

It seems to rely on an analog input voltage on the negative power pin to set the brightness. Add to quote list.
