FAQ For LED cabinets of large led display

• 1 Q: How to calculate the resolution of led cabinet?
• A: Resolution in horizontal = cabinet width÷pitch
  Resolution in Vertical = cabinet height÷pitch
  For example a P16mm 1024mm x 768mm led cabinet resolution is: 64 x48 pixels
  Resolution in horizontal = 1024÷16 = 64 pixels
  Resolution in Vertical = 768÷16= 48 pixels
• 2 Q: What’s the difference between aluminum and steel cabinet?
• A:The main differences are: weight; anti-rust; price; heat dissipation;
  With same design, weight of steel bare cabinet housing is around 2.2 x weight of aluminum cabinet, the exact ratio for the material in same cubige is: aluminum: steel = 2.7: 7.8 .However, the difference of the complete cabinet is not so big when taking modules, power supplies, locks, hanging structures and material thickness into account. Normally, for aluminum cabinet, we use 2mm aluminum plate while 1.5mm for steel plate.
  Aluminum material is better than steel material on antitrust and anti-corrosive aspect. Aluminum material can not be soldering together like steel cabinet, but using rivets to connect different parts together. The price for standard bare aluminum cabinet is around 3 times higher than standard bare steel cabinet.
  Aluminum cabinet will be better for heat dissipation, which is approximately twice better than steel.
• 3 Q: How to keep the steel cabinet anti-rusted?
• A: As we know, iron and steel material is easy to get rusted, so people use Zinc coated plate to make cabinet to avoid getting rusted. The more Zinc on the surface, the better anti-rust effect we can get.
• 4 Q: Why make cooling and heating system for the cabinet ?
• A: The working temperature for led display is -20℃～40℃.Within this range, the lower the better. In order to guarantee the led display in good working temperature, the manufacturers will keep good ventilation for the led display. Normally, there are fans inside the cabinet or A/Cs outside the cabinets as cooling system. If the temperature is extremely low like in Russia, it will be better to add some heating strips in each cabinet as heating system.
• 5 Q: What Certificate do you have for the products?
• A: Bare cabinet housing, modules, power supplies, fans, data receiving card, data and power connectors.
  

  Bare cabinet housing	Modules Indoor
  Modules Outdoor	Switch Mode Power Supply (SMPS)
  Fan	Data receiving card
  Data and Power connector	Fast Lock

• 6 Q: Can the cabinets design customize?
• A: Yes. We can design the cabinet as close as we can to meet the dimensions and colors required by customers.
• 7 Q: What is weather proof for the outdoor use cabinets?
• A: Front: IP 65; Rear: IP 43
  IP code (EN60529/IEC529) stands for Ingress Protection. First number means code of Protection against solid objects and Second number means code of Protection against liquids.
  

  I		P
  0	Non protection	0	Non protection
  1	Protected against solids objects over 50mm (e.g. accidental touch by hands	1	Protected against vertically falling drops of water
  2	Protected against solids objects over 12mm (e.g. fingers)	2	Protected against direct sprays up to 150 from the vertical
  3	Protected against solids objects over 2.5mm (e.g. tools and wires)	3	Protected against direct sprays up to 600 from the vertical
  4	Protected against solids objects over 1mm (e.g. tools, wires and small wires	4	Protected against sprays from all directions - limited ingress permitted
  5	Protected against dust - limited ingress (no harmful deposit)	5	Protected against low pressure jets if water from all directions - limited ingress permitted
  6	Totally protected against dust	6	Protected against strong jets of water e.g. for use on shipdecks - limited ingress permitted
  		7	Protected against the effects of temporary immersion between 15cm and 1m. Duration of test 30 minutes
  		8	Protected against long periods of immersion under pressure

• 8 Q: How many designs of cabinets do you have?
• A: By installation: Rental cabinets design and fixed cabinets design;
  By application: Sports perimeter design; stage/back ground design;
  By material: steel cabinet design; aluminum cabinet design; stainless cabinet design;
  By environment: indoor cabinet design; outdoor cabinet design;
• 9 Q: What is the maximum weight of cabinet that the hanging structure can support?
• A:  Not more than 500 kg.
  If the complete cabinet weight is 70kg, it means that the maximum cabinets quantity is 7 pcs.
