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.
Sistem tenaga listrik yang stabil merupakan salah satu landasan bagi pengoperasian LED yang andal.
Layar LED berukuran besar biasanya mencakup:
- konsumsi daya yang tinggi
- beberapa rangkaian
- transmisi tenaga listrik jarak jauh
- sistem cadangan
Mengapa Stabilitas Daya Penting
Pasokan listrik yang tidak stabil dapat menyebabkan:
- fluktuasi kecerahan
- signal interruption
- kerusakan catu daya
- ketidakstabilan modul
Ini menjadi sangat penting dalam:
- iklan luar ruang
- XR studio
- pusat komando
- acara langsung
Mengapa Layar Besar Membutuhkan Sistem Distribusi Multi-Sirkuit
Sistem LED berskala besar biasanya mendistribusikan daya ke beberapa sirkuit untuk mengurangi beban.
Proyek-proyek profesional sering kali mencakup:
- penyeimbangan sirkuit
- perlindungan mandiri
- sistem cadangan
- perlindungan terhadap lonjakan arus
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.
DDW Engineer Notes: LED screen power distribution
Dalam banyak proyek di luar ruangan, kualitas daya secara langsung memengaruhi stabilitas tampilan dalam jangka panjang.
Terutama di wilayah-wilayah dengan infrastruktur kelistrikan yang tidak stabil, distribusi listrik yang tepat menjadi sangat penting.
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.
