DIY LED meanwell driver issue.

I have an arduino Uno setup on a basic sketch to output PWM at full tilt

with no LED's hooked up, my volt meter will not read above 33 volts, even when the driver is cranked up to full. To top that off, it took almost an hour for it to climb to 33 volts from the 18v it started at.

what am I doing wrong?

Thanks in advance.

Very interesting that your voltage is climbing the longer they're plugged in. I'm trying to work through a similar issue: one of mine is at 18V and the other is at 24V when the drivers are plugged in with no LEDs attached. I never left them plugged in to see what the voltage did over time. I haven't made any adjustments to mine.

I've yet to hear back from Martin with regards to the voltage out of the drivers, but it does seem odd.

it seems like this is how they behave when

A) its not under load
B) there is now dimmer source attached

with my LED's hooked up I am pulling 51v and they are ridiculously bright
