It is a standard LED display / cabinet power supply label. The main visible text includes:
• Model: (appears to be something like S-300-5 or similar variant; exact model number is partially obscured but common for 5V LED modules)
• Input: AC 100-240V 50/60Hz (approx. 4-5A depending on exact rating)
• Output: DC 5V (high amperage, likely 60A or 300W class for LED panels)
From the label, each cabinet is 500 mm × 500 mm (0.5 m × 0.5 m).
So the area of one cabinet is:
0.5 m × 0.5 m = 0.25 m2
8 cabinets:
8 × 0.25 m2 = 2.0 m2
So:
One cabinet: 0.25 m2
One box (8 cabinets): 2.0 m2
5 boxes (40 cabinets): 10 m2 of LED screen.
So the total screen size is approximately 10 square metres.
