KEY TECHNOLOGY |
Conversion efficiency |
Adopt synchronous rectification technology to ensure: AC-DC converion efficiency > 86% (when outputting 60A) |
power factor |
Adopt active compensation technology to ensure power factor ≥ 0.98 |
Dynamic Load Characteristics |
When the output current changes from 0 to 60A, ensure that the output voltage changes ≤± 5% |
Electromagnetic Compatibility |
Comply with ENS5022 Class B (or GB9254-2008) standard |
Aluminum electrolytic capacitor brand |
Rubycon (Ruby), N.C.C (Black King Kong), Nichicon (Nahipu) |
MOS tube brand |
Ixys (USA), ST (STMicroelectronics), Fairchild (Fairchild) |
Cooling fan |
Adopt double ball bearing technology to ensure: fan life ≥ 50,000 hours |
Module base and mask |
The module base and mask are made of flame retardant PC material (flame retardant grade VD), and the flame retardant grade test report provided by the authoritative organization is provided. |
Driver chip |
LED display dedicated constant current driver chip. |
Energy-efficient technology |
Maximum power consumptions ≤ 0.8KW/m²; Average power consumption ≤ $0.32KW/ (low heat, high reliability, long life) |
Data transmission |
Two-wire hot standby technology is adopted to ensure the reliablity of data transmission, and a star connection is adopted between the control board and the module in the screen (serial connection is rejected) to prevent the failure of one connector and cause the chain failure of a series of modules |
Module-level point-by-point correction technology |
There is a point-by-point brightness correction function to ensure that the brightness uniformity between pixels is less than or equal to 5%, and the brightness uniformity between modules is less than or equal to 5%; The module is equipped with a CPU and memory, and the calibration data is stored in the module, and the uniformity is intelligently processed by the CPU in the module. Ensure that modules can be replaced quickly and easily. |
