Let me know if it works

Ok so went back into basement and hooked up V- to GND Pin & V+ to 24v. I was able to get the single channel driver to show power (blue led indicator) then when I touched the LED - wire to a - portion of the LED the + LED wire is currently soldered to the chip would start to smoke immediately (the led did power on though. If I switch the V+ to the DIM pin the chip begins to smoke immediately after plugging the power supply in. Now what’s weird is if I transfer the wires over to the dual channel driver it won’t even power on.

Jump from dim to 5 volt
Run power from 24 volt to 24 volt

Jump from dim to 5 volt
Run power from 24 volt to 24 volt

Smoke as soon as I touch the LED - to the led chip.

I shouldn’t work with the power hooked up through the dim

It might be worth emailing Steve’s for a diagram and waiting

Don’t know about the smoking unless the driver isn’t reducing the voltage enough for the led chip I think they would drive 1-6 without issue

I might have to just send them an email. Wondering if maybe the dual channel driver is just bad and is why it’s not indicating it has power when I transfer the wires to it from the single channel.

Yeah its should power up with same hookup my concern would be it’s pushing to much power for the chips I would ask Steve’s how you determine which mA driver it is 750mA would be what you need for 3 watt led

 

[cooltowncorals]

Is the led on a heat sink it might require that as well

Yes all LEDs are on a heat sink.

I really appreciate all your help though!

Hello,

I’m curious not sure if you thought of this but most cree leds have a longer end which is the positive and the short side is the negative. If you have any of these reversed that would also cause your problem of smoking and not working. I would also test each led individually to make sure the diode hasn’t been burnt up.

Lemme catch up on this and I will help if I can.

Once you have smoke you have parts that are done for or are very short lived

Wait for Steve's to get back to you and then order the smoked parts.

I am looking through your photos. And will try and figure out what happened as well.

Sorry this happened.

All the LEDs are labeled as to the -/+ points. All LEDs are fine & illuminate. The LEDs are not all soldered together and this point.

I really hope they’re not smoked. I just purchased these and was told everything was new.

If you've sent 24 volts to the dim connection you've wired it wrong and those drivers will be toast. I use meanwell ldd drivers on my set up, the dim is connected to the pwm output of my DIY version of the storm/hurricane X controller, so I guess you need to connect the positive from the potentiometer to the dim and the other to ground?

Hopefully the LEDs should be ok.

According to the only Steve’s led wiring diagram I could find this is how I wired it. The single channel driver still work, however I was never able to get the dual channel driver to indicate it was on.

It seems, though I maybe wrong that you've connected the 5v out to the 24 v in and have 24 volts +ve from the psu to the dim?

 

[CCK_8814]

Per diagram above, V+ wire from power supply was run to the DIM pin & then was tried both with & without a jumper from the 5v pin to 24v pin.

Pwm is the one labelled dim, +24v is from the psu, jumper is from the +5v output on the board to the dim, this is to allow dimming control via a potentiometer. I'm afraid you've dropped 24 volts to the pwm connection, which means those drivers are toast, don't worry we all make mistakes, I've blown up a few bits of kit during my build by being careless and having stray wires from a 48v PSU blow up controllers whilst searching for a loose contact....
