Topic: Need 10v PWM signal (Read 1 time) previous topic - next topic

I need to learn how to convert the 5v PWM single that the Arduino produces and convert it in to a usable 10v PWM signal to control drivers for an LED light system.

Thanks for the help

feed a transistor 10 volts and modulate its base at 5

Sorry, my crystal ball isn't working today.

What "driver"? What "light system"? Where would you get 10V from? etc.

I'm using a Meanwell LDD-700HW and it will have 12 Cree XT-E LEDs on it. The 5v PWM signal is coming from an arduino mega 2560.  I need to convert the signal to 10v PWM to dim the LDD driver.

According to the datasheet the PWM input of a Meanwell LDD-700HW needs 2.5-6V. 10V would break it.

It will break it. Trust me. Twice burning boards was due to using more than 5V. As everyone says, we don't completely understand what you're doing. If anything, plug in a 10V source and use the Vin to get the 10V back (in an Uno, for instance). All you should need to do is use the 10V for power. Everything else is done with 5V (buttons, etc).

Basically, use only the 10V for power. Touch nothing else with it. You will not be happy with results of burning boards.

Hope this helps.
