1 |
Conversion efficiency |
Using synchronous rectification technology to ensure: AC/DC conversion efficiency ≥86% (when outputting 60A) |
|
2 |
power factor |
Active compensation technology is used to ensure: power factor ≥0.98 |
|
3 |
Dynamic load characteristics |
When the output current changes from 0 to 60A, ensure that the output voltage changes ≤±5% |
|
4 |
Electromagnetic Compatibility |
Comply with EN55022 ClassB (or GB9254-2008) standard |

||
Key technology |
|||
1 |
High efficiency and energy saving technology |
Maximum power consumption ≤0.8KW/㎡ Average power consumption: ≤0.32KW/㎡ (low heat, high reliability, long life); |
|
2 |
data transmission |
Adopts dual-line hot backup technology to ensure the reliability of data transmission; A star connection is used between the control board and the modules in the screen (rejecting serial connections) to prevent the failure of one connector from causing a chain failure of a series of modules. |
|
3 |
Module-level point-by-point correction technology |
It has a point-by-point brightness correction function to ensure that: the brightness uniformity between pixels is ≤5%, and the brightness uniformity between modules is ≤5%; The module is equipped with a CPU and memory. The correction data is stored in the module, and the uniformity is intelligently processed by the CPU in the module. Ensure modules can be replaced quickly and easily. |
|
4 |
Color reproduction |
Use color space transformation technology to adjust the red, green and blue coordinates to improve the color reproduction of the pattern. |
|
5 |
LED downtilt angle |
In order to increase brightness, increase viewing angle, improve uniformity, save energy and extend life, LEDs can be tilted down from 3 to 8°. |
