DVDdoug:
You can't dim/PWM a relay and with the Mean Well you don't need a relay.
The Arduino has an on-board 5V regulator. So typically, you'd use a ~10V power supply. Then, you just add a transistor, connected to 10V, to "boost" the Arduino's 5V PWM.
I don't want to control relays through a pwm signal. I just want to create a power strip to switch on/off the drivers (ac side) with relays, nothing strange.
Then I would like to have additional slots to attach the dim leads to dim the lights through 10v pwm.
Anyway Thx for your replay. May I ask you to explain a bit more?
I can use a 10v power supply and the voltage regulator inside the board will adapt it to 5v?
I don't have to use 2 different AC-DC, am I right?
Are you suggesting to use a transistor like a 2n3904 to control external 10v and arduino pwm signal on Base pin?
How many pwm pins do the Uno R3 has? 6?
Can I individually control 6 different drivers this way? Or is the pwm signal limited by something?
