Is this Mean Well driver too much for...

Hi,

Hope someone can help.

I have a LED grow light that went a bit wrong. It was made up of two panels of 5w LEDS. Some of the LEDs stopped working. The manufacturer kindly replaced the whole panel and also in the problem finding process gave me a new Mean Well driver (LRS-350-4

I was wondering if I could wire up the faulty panel to the spare Mean Well driver. The blue and Red LEDs still work fine on the panel.

I did a quick test and it does light the panel up. I didn't want to leave it on for long because I wasn't sure if the driver was over powering the LEDs. I know I will have to add a heatsink and fan if I want to leave it on.

I am not sure if the driver would push too much power through the panel as it was previously running 2x of these panels. Or if the LED panel actually only draws the required power from the driver.

I hope that makes sense.

Thanks.

if it ends in -48 its prob a constant voltage driver and would be doubling up the current if you cut the lights in half which is prob a death sentence for cheap diodes

Thanks for your reply. The driver does have an adjustment screw that says +V. Would I be correct in thinking this is to adjust the voltage, and I could turn this down to suit the single board/panel of LEDs (using a Multimeter). If I did this would the driver be OK to use ?

So it would be the 48 v I should be concerned about and not the 350 watts?

Thanks again

not necessarily. if the forward voltage of the led string is below 43.2V, adjusting the voltage screw will have no effect at all

In that case I will have to admit defeat on the idea then. I was hoping there would be a way to use these parts.

I made the incorrect assumption that if this driver was powering 2x of these LED panels then I could have a guess at what driver could power 1x of them.

Thanks again for your help.
