Power Adapter for LD686

I have the LD686 for LED-Strips
Now I need a power supply/adapter.
I want to connect up to 4 LED-Strips to it.
Found e.g. this adapters on aliexpress

But which voltage should it take? 24V with 5A ?


It depends on how much power your strips will use.
If you have 4 strips at 5V and each using 1A then you are using a total of 5x4=20 Watts

If you use a 24V power supply then I would use a 2A rated one just to be on the safe side
The 1A rated one would deliver 24x1=24W
The 2A rated one would deliver 24x2=48W

BUT be careful with the rating of your strips. and your controller CANNOT deliver more than 1.25A to each strip.

The adapter of my printer is also not working. When I am trying to connect the printer with my system through its adapter is not getting connected and it is also showing Epson printer error code 031008 on the interface.

Hi @vzorglub,
thanks for your answer.
I currently have 3x 12V-LED-Strips (I don’t see, if it’s 1A or 2A)
I want to another LED-Strip --> so I want to use 4 LED-Strips with that controller.

Will one of this adapter work? or should I prefer this one?

Thanks again,

According to the led specs, they use 4 watts per meter.
So you needs to measure the strips and do some maths

Hi @vzorglub

One LED-Strip is 5m long.
–> One LED-Strip 5 x 4 = 20W correct?
When using 4 Strip, I need 80W ?
So, when I take this one I could have 72W max, right? (when selecting 24V*3A).
Would that work well?


No, your supply is 72w max
At full brightness it will overheat and fail
You need at least 4amps,better get 5 amps
But your check your controller too

This is a the photo from the Wi-Fi controller.
Does that mean that I only can use one stripe at this controller?

No you can have 5 outputs at 4 amps each. You controller should be fine
