This product is a constant current plate, the focus is constant current, the voltage is automatically adjusted, and the voltage is automatically adjusted according to the string of the light backlight module, such as: when the backlight module 4 and 20 strings, the voltage is adjusted to 3.2 V string * 20 = 64 V around, assuming that each string of LED current is 60 MA then only need to set the current 240 MA to point this screen.Features:Taiwan imported original program manufacturing, improving the conversion efficiency of the structure by more than 92%.The product has low heat and stable products and has a longer life.The PCB is small in size and ultra-thin design to meet the most demanding requirements.Accurate current control error of 5%, flexible and convenient current adjustment design can be easily modified to match different manufacturers, screen models.Designed to meet EMC requirements and CE certified. High reliability, one year warranty! 12V power supply can be used to reduce system cost!The iron silicon aluminum magnetic coil winding system has a high temperature coefficient, a high magnetic saturation rate and a high stability.Because the system conversion efficiency is very high, the heat of the equipment is very low, the temperature is controlled at 25 C (Note: temperature = equipment surface temperature (ambient temperature), environment 25 C, the surface temperature is the highest 50 C (working conditions: input 24V, Output 64V 480ma).Limit parameters:24V input: Vout = 75V Iout = 720mA or 60W12V input: Vout = 75V Iout = 400mA or maximum 30WThe limit parameter refers to the maximum bearing capacity of the product during the application process. In actual use, please use it below the limit parameter to ensure the reliability of the product.Specification:Material: PCBColor: greenSuitable size: 15-42 inchUses: LED LCD TV boost constant current backlight driver boardInput voltage: 10-28VOutput: 15-88VOutput current: 10-1000MA can be set, typical: 480MASize: Approx. 8.5 * 4.5 * 1 cm / 3.3 * 1.8 * 0.4 inPackage Weight: 25 gPackage list:1 * Constant Current Driver Board.Note:Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering.
