10-42 inch LED TV Backlight Board LCD TV Backlight Board Constant Current Board Boost Board Backlight CA-255

 

Description:

Product features: Made in Taiwan original imported program, BOOST structure, conversion efficiency of more than 92%, low heat generation, stable product, longer service life, small PCB size, ultra-thin design, to meet the most demanding requirements, accurate The current control error is within ±5%, and the flexible and convenient current adjustment design can be easily changed to match the screens of different manufacturers and models. Designed to meet EMC requirements and CE certified. High reliability, one year warranty! You can use 12V power supply to reduce system cost!

 

This product is a constant current board. The focus of the work is constant current. The voltage is automatically adapted. The voltage of the backlight module is automatically adjusted. For example, when the backlight module is 4 and 20 strings, the voltage is adjusted to 3.2V*20. String = 64V or so, assuming that each string of LED current is 60MA, then you only need to set the current to 240MA to click on this screen.

 

It is made of iron-silicon-aluminum magnetic ring inductor, higher temperature coefficient, higher magnetic saturation and higher stability. Due to the extremely high conversion efficiency of the system, the heat generation of the device is very low, and the temperature rise is controlled at around 25 °C (Note: temperature rise = device surface temperature - ambient temperature). When the temperature is 25 °C, the surface temperature of the component is up to 50 °C (working conditions: Input 24V, output 64V480MA.)

 

Limit parameters:

At 24V input: Vout=75V Iout=720mA or up to 60W

 

At 12V input: Vout=75V Iout=400mA or up to 30W

 

The limit parameter refers to the maximum bearing capacity of the product in the application process. In actual use, please use it below the limit parameter to ensure the reliability of the product.

 

Package include:
