Hi, I would like to prepare Christmas tree light show with 2 LED strips WS2811:

2X LED strips:

They say each meter of the LED consume 3.6 Amps. So 2 strips of 5 meters each would consume 36 Amps.
Will this power supply do the work?

PowerSupply:

I intend to use this with Arduino Uno and Glediator and FastLed.

Thanks

2x5m would consume 36 amps maximum, and that supply will certainly be suitable (assuming the reviews don’t suggest otherwise).

Fanless design and very, very little parts. I expect massive voltage overswing when switched on and quite some ripple. Can’t see any voltage adjustment. Make sure you check the power supply first with an oszilloscope. Just to make sure it won’t kill your LEDs.

Thanks for your feedback @Juergen_Bruegl and @1icri_Old_Account . @Juergen_Bruegl can you suggest a power supply that would be safe for me to use for this setup? I have children in the house and quite new to electronics. Thanks

The Meanwell SP-240 and SP-320 are not bad.

how large a sheet of aluminum does it require to not overheat when running near full 40 amps?

@Juergen_Bruegl Thank you for the suggestion. I will buy something like that. Can you tell me what I need to hookup the LED strips to this power supply? Would something like this works? https://www.amazon.com/Maxmoral-Female-Power-5-5mm-Adapter/dp/B00XJ23U3A/ref=pd_bxgy_267_img_3?ie=UTF8&psc=1&refRID=2QMA2T7S0HB19R3ZQM1K

40 Amps considered I would go for the good old Molex PC Power connectors. You need at least 3 pins

@PaulStoffregen the Power supply design is open frame, that means the heat dissipates upwards. If a large sheet of aluminium or heat sink

Closed desings have a vertical fan airflow and the Fets and Voltage Regulators are internally on a massive heat sink.

In general those power supplies have an efficiency of 75-80%, that means in order to get 40A you have to get rid of approx. 80 Watts of heat.

@Juergen_Bruegl Thank you

Just a thought… running them at full bright in the dark might actually be too much for the neighbors. At night, I’m sure you can easily run them at half bright (half the amps) and barely notice any decrease in the effect.

@allanGEE Thank you! This project will be inside so it won’t be a problem I think. However like you said, I won’t need to go full brightness.
I just need to be able to control the 2 LEDs strips with Arduino and using Fastled for animation. I saw Glediator the other day, it seems quite simple to animate a led matrix. Maybe I could use that program to animate my 2 LEDs strips. I would like it to react to music also. Any thoughts are welcome.
Thank you
