3W-9W RGB LED hookup question

by chrisbienert on Thu Aug 10, 2017 4:18 pm

3W-9W RGB LED - Common Anode
PRODUCT ID: 2524

Hello,

I am trying to figure out if i can use this directly with a constant voltage led controller. I couldn't find anything in the data sheet.

Thanks,
Chris

What are the specs for the controller?

Its a constant voltage driver that receives DMX 512 signal and converts to pwm signal. Input voltage can be between 12 - 36 volts and supply up to 5 amps per channel.

Hope that clarifies things a bit

Thanks!

You'll need to control either the voltage or the current.

The red LED's forward voltage is 2.5v @ 350mA. The green and blue LEDs have the same forward voltage of 3.6v @ 350mA.

The 12v-36v @ 5A channels you described would kill the LEDs as soon as the current started flowing.

ya you definitely will need a step-down converter for each LED that is constant current. we don't stock any but check out

Perfect I ordered the 9 watt rgb led and the constant current driver yesterday thinking "well just in case" so I am glad that I did now. Thanks for your help!
