26-55 Pulgadas Universal Led Lcd Tv Placa De Corriente Const. * Este producto viene desde China DESCRIPCIÓN Features: 1. LED TV backlight drive, 26-55 inch backlight module. It is a universal LED backlight board. 2. Constant current output: 200 mA. The current can be self-regulated according to actual needs. 3. Simple, convenient and fast current setting device: Easy to deal with the LED current difference between different panel backlight modules. 4. Usage: connect the soldering iron to the welding point indicated by the arrow to increase the current (brightness). The resistance decreases, the current increases, the resistance increases, the current decreases. 5. LED output terminal, 60-165V automatic adapting. Specification: Material: PCB Color: Green Purpose: 26 "-55" LED TV Display Voltage: 100V-165V Input Voltage Range: 22-42V DC Output Voltage Range: 65-165V DC Output Current: 10mA-1000mA (can be set) Size: Approx. 12 * 6 * 1.2 cm / 4.7 * 2.4 * 0.5 in Package list: 1 * Constant Current Plate Precautions Before Purchase: 1. The operating voltage of the light bar must be in 60V-165V between the arbitrary voltage. Not less than 60V, if less than 60V you can choose to buy my shop other goods. Can not be higher than 165V, the product design limit working voltage conditions shall not be higher than 165V, more than this voltage will appear screen dark or flashing lights and so on. This product is only constant current, not constant voltage, the voltage will be based on the needs of the lights. Automatically adjust the voltage to the appropriate voltage, so you do not need to tangle in the no-load when the measured voltage is the number of volts. 2. The actual parameters completely beyond my product parameters; (such as: light bar voltage needs 180V above will not be driven...) General parameters: 60V-160V 200MA @ 24VIN Problems that may be encountered with proper lighting: Brightness is not enough, the screen is significantly darker than the original board, this time from two aspects.  First, connected to the dimming feet after trying to try to adjust the brightness of the remote control can be resolved, if not solve, to test the actual feet Bit voltage, (Note: Our products 0V When the brightness of the darkest, darkest when the voltage is high.) If the voltage range is analog voltage mode is 0V-5V or 0V to 3.3V, and if the voltage has been at a high voltage can not be reduced should be adjusted. If PWM the voltage of the signal is stable 3.3V, this time if transferred to the brightest or not meet the requirements of the second program will have to implement.  Second, adjust the board resistance, the current increases, to meet the requirements.   LED Drive Scheme Interpretation: In view of many buyers for the LED driver board topology do not understand, its working principle does not understand the direct result of the consequences can not be properly used! We hereby briefly introduce the current popular topology scheme. The most commonly used topology there are three: boost, buck, boost-buck. 1. Boost topology means boost type. (Vout) must be higher than the power supply input voltage (Vin), and the ratio is greater than 1: 1.5, that is, if the input voltage is 12V, the LED string voltage must be In the 18V or more, then the LED boost board to work properly, if the LED string voltage is slightly higher than VIN or VIN below the situation that occurs when the machine is a power LED lights up, driving the board switch, dimming, etc. can not Consequences of Control. Boost program has the advantage of simple structure, high efficiency. The disadvantage is that the boost ratio is limited, generally the best boost ratio of 2-4 times. More than 6 times when the switching loss increased sharply, the switch device temperature soared, the system stability deterioration. 2. Buck topology means the buck type. (Vout) must be lower than the power supply input voltage (VIN), that i ESPECIFICACIONES
