③Temperature standard requirements: working environment temperature -20°C≤: T≤80℃ storage environment temperature -40°C≤: T≤60℃;
④The power supply voltage must meet the standard requirements:
The power supply voltage of the LED display: 220V±10;
Ensure safe grounding, separate wiring of the ground wire and neutral wire, and keep the access voltage away from high-power electrical equipment.
The quotation of the full-color P3.91 LED display is mainly affected by the following factors:
1. Quotation of the screen body: that is, the price of the conference room display screen is ××yuan/square meter, and the selected materials are different, the price is also different, including the cost of LED die, IC drive chip, power supply and LED cabinet.
2. Control system cost: that is to control the computer and the number of receiving cards and sending cards, the number needs to be determined according to the size of the LED screen in the meeting room, and then the cost is calculated.
3. Auxiliary equipment costs: power distribution cabinets, computers, audio amplifiers, air conditioners, control cards, lightning arresters and LED video processors, etc., can be selected according to requirements, and customers can buy them themselves.
4. Display screen playback software: including computer system software, as well as LED video playback software, etc., generally free of charge.
5. Steel frame structure cost: including manual installation cost. Generally, the steel frame column structure is more expensive than the wall installation structure. You can also ask the LED display manufacturer to provide the steel frame structure design drawings, and the customer can find the local manufacturer to make it.
6. Transportation cost: the cost of logistics transportation is paid by the customer.
7. Installation cost: When the goods arrive at the site, the technical engineer of the LED display manufacturer will come to assist in the installation and commissioning. The installation is free of charge, but the general board and lodging expenses and round-trip travel expenses of the technical engineer are required.
How to calculate the price of full-color P3.91 LED display?
