4 Lamp Backlight Universal LCD CCFL Inverter 10-30V for 15-22" Screen Universal Replacement

Led Lcd Driver and led TV back light driver board TV constant current board boost universal modification

Uses: 10-42 "LED TV backlight boost board.

Features: Taiwan imported original program manufacturing, BOOST structure, the conversion efficiency of 92% or more, the device fever low, stable product, has a longer life, PCB small size, ultra-thin design to meet the most demanding thin and light requirements, accurate Of the current control error within ± 5%, flexible and convenient current adjustment design can be easily modified to match different manufacturers, models of the screen. Designed to meet EMC requirements, through the CE certification. High reliability, one year warranty! Can use 12V power supply, reduce system cost!

 This product is a constant current board, the focus is constant current, voltage is automatically adapted, depending on the backlight module light string automatically adjust the voltage, such as: the backlight module is 4 and 20 strings when the voltage is adjusted to 3.2V * 20 String = 64V or so, assuming that each string of LED current is 60MA then only need to set the current to 240MA can point this screen.

The use of iron-silicon-aluminum magnetic coil wound system, a higher temperature coefficient, higher magnetic saturation and higher stability. Because the system conversion efficiency is very high, so the device heat is very low, temperature control at 25 ° (Note: Temperature = device surface temperature - ambient temperature), when the environment at 25 °, the surface temperature of the highest 50 ° (working conditions: Input 24V, output 64V480MA.)
