CA-266S 32-65 Inch LED LCD TV Backlight Constant Current Driver Board 80-480mA Output

Specifications Input Power 10 28V DC InputOutput voltage 88V automatically adapt to the following the minimum limit for the input voltage no buck Output current default 80mA by shorting R22 R21 R18 R15 R24 resistance can increase the current each resistance 80mA Up to 480mA Applicable light bar Large size 26 inch 65 inch maximum voltage 88V Input Interface Definition 1 Power supply 2 Power supply 3 ENA switch control 4 Brightness adjustment signal voltage dimming 5 Ground wire 6 Ground wire Output interface definition Positive and negative There are four parallel interfaces the same definition Features 1 with protection 2 Output voltage below 88V automatically 3 change the current is convenient the motherboard has six 1206 resistance a resistance of 80mA up to 6 resistance is fully connected to 480mA 4 default only connected to a R13 resistor the output current of 80mA will not burn light bar If it is too dark flashing or flashing off try to increase the current Until the normal brightness light can not be hot 5 no load will not burn the board in the case of no load or bad light output voltage will drop to the input voltage or in the case of load voltage higher than 88V will be reduced to the input voltage value 6 with 4 output interface the general definition of in the then 2pin left and right of the right light of the interface directly to the middle of the 2 3 pin can be 1 4 pin empty Tips 1 If you donot
