10-48 inch LED LCD TV Backlight CA-255S Constant Current Board Boost driver Inverter board CA-255 Universal 10-42 inch LED LCD

Package : SMDis_customized : YesModel Number : CA-255Operating Temperature : LED TV Constant Current BoardDissipation Power : LED TV Constant Current BoardSupply Voltage : LED TV Constant Current BoardApplication : ComputerCondition : NewType : Voltage RegulatorBrand Name : diymore : Mainland ChinaCA-255S 10-48 inch LED LCD TV Backlight Constant Current Board Boost driver Inverter board CA-255 Universal 10-42 inch LED LCDDescription:·Common Electronic symbolic e of Backlight: 1. VCC: The positive of voltage supply, Circuit supply voltage (voltage is usually 12V or 24V) 2. ON/OFF,ON,EN,ON_BL: Switch signal pin 3. PWM,PDIM,VDAJ,BL-PWM: Brightness adjusting pin 4. GND: Ground (negative electrode) 5. LED+: the positive electrode of Light emitting diode (lamp) 6. LED-: the negative electrode of Light emitting diode (lamp) Application: Product features: ·10-42 inch LED Backlight Lamp Driver Board Constant current board ·BOOST structure ·Conversion efficiency reached more than 92% ·low heat of the Device, stability,have a er service life ·the PCB is small,Slim design,Current control error within ± 5% ·You can use the 12V power supply to reduce the system cost! ·This product is constant current board, voltage is automatically adapted ·The temperature rise is controlled at about 25degrees (Temperature rise = device surface temperature - ambient temperature) ·Limit : When to 24V input: Vout = 75V Vout = 720mA maximum or 60W When to 12V input: Vout = 75V Iout = 400mA maximum or 30W Warm Tip:Limit parameter refers to the the maximum capacity when product in the application process.In fact,please under the limit to ensure product reliability when using. This product is a constant current plate, the work is focused on constant current, the voltage is automatically adapt, depending on the backlight module string automatically adjust the voltage, such as: backlight module is 4 and 20 string when the voltage for their own adjustment 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.Using iron-silicon-aluminum material magnetic ring inductance wound, higher temperature coefficient, higher magnetic saturation and higher stability. Due to the high conversion efficiency of the system, so the device is very low heat, the temperature control at 25 ℃ or so (description: temperature = device surface temperature - ambient temperature), when the environment in the 25 ℃ surface temperature of up to 50 ℃ (working conditions: Input 24V, output 64V480MA.)
