ขาย Universal 10-42" LCD LED TV Backlight Driver Board Constant Currentdfsd2021 ePaX ราคาที่ดีที่สุด

Features: It can be used for 10-42inch LED TV backlight booster board. BOOST structure, conversion efficiency of more than 92%, low heat generation, stable product, longer service life, small PCB size, ultra-thin design. 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 for EMC requirements and CE certified. The voltage is automatically adapted, and the voltage string of the backlight module is automatically adjusted. The focus is on the constant current. Wound with magnetic silicon ring magnetism, higher temperature coefficient, higher magnetic saturation and higher stability. Compared to the Gold-16E, this product adds current regulation function. Specifications: Material: PCB Input Voltage: 12-25V Output Voltage: 35-85V Output Current: Default 100MA(can be increased to 800MA) Absolute rating: 24V Input: Vout=75V, Iout=800mA or 60W Max 12V Input: Vout=75V, Iout=400mA or 30W Max Current adjustment: 30-200mA Suitable TV/Monitor Size: 12-24inch Package List: 1 x Driver Board Note: You need to have a certain basic knowledge of physics and electronics, and you need to have a clear understanding of the core components of liquid crystal displays, LCD TVs and other products. 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. Backplane common electronic symbol code Chinese and English are as follows: A. VCC: The supply voltage is positive, the circuit supply voltage (voltage is usually12Vor24V) B. ON/OFF, ON, EN, ON_BLWait: Switching , switching signal (voltage range is usually in2.5V-5Vbetween) C. PDM, VDAJ, BL-PWMWait: Brightness adjustment feet, or called dimming feet. (Dimming will have two modes, one is the digital mode-PWM, One is analog dimming-DC. PWMCalled pulse width modulation, which produces a rectangular Square wave signal, the frequency is generally200HZ-2KHZ,The magnitude of the voltage is usually3.3V, & Lt;PDIMIs the English abbreviation,DimIs the meaning of the dark meaning of the word meaning that "brightness." Analog dimming is carried out By means of a DC voltage, usually provided directly to the tuning pin0V-5VofDCVoltage to control the brightness of the purpose. GND: ground (power supply negative) LED +:Light -emitting diode (light bar) positive LED-:Light-emitting diode (light bar) negative The above symbols contain most of the LCD motherboard with the backlight on the code, the connection as long as the corresponding code in accordance with their respective access will not be wrong. Frequently Asked Questions Before Purchasing: Question 1: installed bright not up? 1. Check the polarity of the cable is correct? LED positive and negative are correct. 2. Measure the supply voltage to see if there is no voltage to the board, the machine boot state to measure the LED + there is no รอคอยที่จะให้ความสนใจที่แข็งแกร่งของคุณ
