Quick answer: LED screen power distribution splits the display load across several protected circuits, usually from a three-phase supply through a power distribution cabinet. Design for maximum power but expect average consumption around one-third of maximum, add sequential power-on to avoid inrush current, and ground the system properly.

- 独立した保護
- バックアップシステム
- サージ保護
Power Planning Example
A 20 m² outdoor LED display with a maximum power of 800 W/m² needs about 16 kW at peak, while average consumption is typically around 5–6 kW. The load is balanced across three phases, split into several circuits with their own breakers, and switched on in sequence by a power distribution cabinet with surge protection and a ground connection.

FAQ
How much power does an LED screen use?
It varies by product. Indoor LED screens often draw around 150–300 W/m² on average, while outdoor LED displays can average 250–450 W/m² and peak much higher.
Why does an LED display need sequential power-on?
Switching many power supplies on at once creates a large inrush current that can trip breakers. Sequential power-on switches circuits one by one.
Does an LED screen need grounding?
Yes. Proper grounding protects people and electronics, reduces interference and is required for lightning and surge protection.
