Help w/ Retrofit LED PLEASE? Light quit working

[duganderson]

I bought a used Red Sea Max 130D with a DIY Rapid LED like LED. It uses approximately 30 leds on a heatsink- all are CREE XP-E on two Mean Well ELN-60-48D (one for blue and one for white).

I transferred all my coral and fish from my previous tank yesterday. The light worked at first. At night, I turned the dimmers on both channels (blue and white) all the way down with the dimming knobs which shut the light off (I think the previous own did this all of the time). After the lights were off for a while, they flickered very briefly even though the dimmer knobs were all the way down. When I tried to turn them on later using the dimming knobs, they would not turn on and still won't turn on.

Do you have any ideas what might be wrong or what I may check?

There are two power cords.....one that seems to run the lights and fans and another on a thin cord with plug that says input 240 v., output 10 V. 500 mA.

I live in the Minneapolis area if anyone is local and would be willing to help out. I can remove the hood easily to bring to you.

Thank you VERY much, Doug

The 10v power supply is what controls the dimming for both drivers. I would check the output voltage from that, as well as checking the output voltage from the dimming potentiometers. Make sure that's working first. It's the most likely point to check seeing that neither driver is lighting up the LEDs.

 

FYI, the blinking with the dimmer turned all the way down is normal. These drivers don't dim to 0%, and anything less than 10% output will produce this effect. Really, to turn off the LEDs, you need to kill the AC power to the drivers for them to be fully off at night.

I disconnected the two wires after the dimming knobs and attached a voltmeter and they read 10 Amps regarless of what the dimmers were set at. Is that what should happen.

Thanks, Doug

Amps?

 

You may need to upload a few pictures to see if there are any obvious issues with the wiring.

Volts....sorry.

 

Actually, I found someone in my area is working on it for me. Thank you for your assitance.
