Power supply for 44 led strips?

[FAQ-Forum-Bot]

I'm thinking of connecting 44 led strips, item no. 50832, in one long row over one 90 degree corner. I wonder if it's enough to only have one single power supply that will provide all 44 connected strips with power? If one is enough - wich one should I use? Can that one be connected to the ordinary 220 V power system in our house? If one single power supply is not enough - then what do I need? Thx a million in advance!

44pcs * item no. 50832 (100mA) = 4,4A@24V (105,6W)

No problems with the current (44 x 0.1A = 4.4A), because 44 strips in a long row isn't a good idea.
The voltage drop is to great, the last strips becomes a lower voltage. Copper has a resistance.

For a long row you need some cable parallel.
Connect this cable after some meters again and again to the strips and at the end of the last strip.
That cable diameter makes the layers diameter greater, the voltage drop is lower.

For 22m (44 strips ea. 0.5m) and a current of 4.4A a cross section of 6mm² is required.
Voltage drop along the entire length: approx. 0.54V
