DIY LED Assistance Needed

[CCK_8814]

Hoping to get some help with a DIY LED Kit I just picked up, hopefully someone here can tell me what I’m wiring wrong and why I can’t get any of the LEDs to light up. The power supply is a mean well & the drivers are Steve’s LEDs. The ground from power supply is going to the ground of the driver, power from power supply to the DIM pin on driver, 24v & 5v pin jumped (have tested with these 2 pins not jumped as well), potentiometer is wired in, but when I try and make sure the LEDs illuminate by taking and running wires from the LED - & positive from the driver to the + & - terminals on the LEDs they do not illuminate. I’ve tried both the single channel driver and dual channel driver with same result. I’ve also made sure to test with the potentiometer turned completely either way. Am I completely missing something or am I wired incorrectly? The green LED on the power supply is on which tells me it’s outputting power. Some pics attached. Any and all help appreciated!

Do you have a volt meter to make sure your getting power to less?

 

[cooltowncorals]

Led?

Do you have a volt meter to make sure your getting power to less?

I do but I didn’t check since I’m fairly sure I have the wiring wrong. I’m done messing with it for tonight but can test and verify tomorrow but I suspect I’m not getting any voltage to the LEDs hence my suspicion I have something wired incorrectly.

What are you driving the LED at 750 1000 500?

What are you driving the LED at 750 1000 500?

I’m not 100% sure honestly. I have a potentiometer installed and have tried with it turned both essentially all the way down and all the way up.

 

[cooltowncorals]

So I looked at Steve’s that driver board comes in 500 750 and 1000 mA so double check and make sure LED and driver match for instance some less need 1000mA to work some need 500

@dantimdad may be able to help with this

I bought the complete kit from another reefer. It has 3w LEDs so I’m assuming that it’s the 700mA versions. I’m not sure how to confirm. Here’s a close up of both drivers.

The wiring I can’t find a schematic did you get one with light?

 

[cooltowncorals]

Do you have 7 or less led hooked up?

 

[CCK_8814]

Do you have 7 or less led hooked up?

No [emoji53] that’s why I’m struggling. Doing my best to go off of pictures I’ve found on google on people posting pictures while doing the Steve’s led retrofit on their biocubes. I was attempting to test 1 led only. Maybe that’s the issue?

One of the connections should be for 0-10v input that they advertise. Might be the 5+ V or the DIM the power supply looks good wiring wise my guess would be that the 24v power from the power supply goes to the 24v input and ground to ground and take everything else off except the hookup to the led

 

[cooltowncorals]

After you get led to light up at full power then put the potential meter back on to dim the light

 

[cooltowncorals]

I would try try power in to 24v and then dim if that doesn’t work all the spots don’t need to be wired there just there for different options

That’s what I thought as well but from my research I was able to find these 2 diagrams which tell me that’s not the correct way. Now whether or not these are correct are another story. I have tried connecting the power supply ground to the GND on driver and power from power supply to the 24v Pin on driver with no luck either.

 

[cooltowncorals]

The +5 could be for pwm or on off switching and dim could be for 0-10

 

[cooltowncorals]

Ok so

take the wire you have on V- from power supply and put on any of the G inputs

run the power from V+ to the 24v input

The dimmer switch is in right place doesn’t look like positive or negative matter

Make sure you have -+ hookup right on led

Try it that way

If that doesn’t work put jumper from dim to +5 then try it that way

 

[cooltowncorals]

The DIM could be the pwm input impossible to know with out schematic so that’s why it would require you to give it 5 volts for driver to work which is why you would jump from the 5v output to the dim input

 

[cooltowncorals]

So a pwm signal is 5 volt for on, 0 volts for off and inbetween for dimming so you most likely need to jump between the 5volt and the DIM (after thinking I bet that is the pwm input)
