Hi. i have 50 rows of 90 leads each. 4.500 Not an electrician. I am been guided by AI's. I think i will not trust my house on flames to them just yet. this is my best plan. Iam in Argentina, 220 v. So, 14 switches 20 amp 5 v. I could use 60 amp or 40 but i dont want the noise of their fans. So,…

I will put fuses on both sides Main 3 amp Leds 5 amp ( since there is 7 rows of 45 leds per converter)

The OP said, [image] Moris526: Every led is 60ma which I thought at the time was high, but I was busy, so I didn't ask. 200mW sounds a lot more manageable.

[image] Moris526: will put fuses on both sides Main 3 amp Leds 5 amp ( since there is 7 rows of 45 leds per converter) That would limit your led power to about 30% of maximum. So driving them at half brightness would trip your fuse. Probably enough for most of use cases though..

Depends what else is on the same breaker (MCB) The line of defence normally, is CONSUMER UNIT MCB>>INDIVDUAL CIRCUIT>>SOCKET OUTLET>>FUSED PLUG (UK)>>APPLIANCE (EQUIPMENT) FUSE(S). What goes first depends on the nature of the fault. Your own wiring may be different. Not sure what you mean by lin…

Im planing to put the PSU’s on the back of the 1 cm wooden board (mdf) that displays the led strips… should i use copper tape or something to shield the electromagnetism?? Or not necesary?

Where are the Arduino(s) located?

Im using Teensy. In the same side of the PSUs about 20 cm distance. I think its safe i was wondering about the signal in the led strip. I will have PSU-2cm air-Mdf 1cm- led strip copper pad

[image] Moris526: In: 175-265V 50/60Hz 1,28A Out: 5V 20000 mAh 100W Cant find datasheet The output ratings are individual, not both 5 volts and 20A at the same time. Test to be sure.

I meant 5amp fuse for each 45 led strip
