Will the F8 Distro board V1.02 handle a 36V power supply.  I want to power two runs of 3 30W floods through the board.  Max draw should be about 3 amps per outlet.

Thanks,
Randy

No problem. The fuses are 5amps on each output.

The resistors for fuse indication are ~960 ohms so leds would burn bright.

Thanks Dave.  Someone else running these suggested turning the power supply down to 30 Volts.  Also I doubt I run these at more than 50% power at any given time.  They arrive tomorrow so I will be able to do some experimenting before mounting them on the park pavilion.

Running the flood lights at 50% power won't affect the brightness of the small LEDs. As long as you are will to accept their brightness and probable short lifespan, the board will distribute 36v. (The LED resistor value was picked with an expectation of 24v max)

I also have other vendor distro boards without LEDs so I didn't really consider that.

The resistor was selected for 12V or less.
