New CA-266S Universal 32-65 Inch LED LCD TV Backlight Boost Constant Current Board 80-480mA Output DC Controller Board

Note: Please do not connect ADJ pin when testing!

Features:

1：With protection.

2: Output voltage below 88V automatically.

3: Easy to change the current, there are 6 1206 resistors on the motherboard, one resistor represents 80mA, the highest 6 resistors all connected for 480mA.

4: default only connected to 1 R13 resistor, the output current of 80mA, will not burn the light bar. If too dark, flickering or flashing off, try to increase the current. Until the brightness is normal, the light bar does not get hot.

5: not connected to the load will not burn the board (in the case of no-load or bad light bar output voltage will drop to the size of the input voltage, or in the case of load voltage higher than 88V will also be reduced to the input voltage value).

6: with 4 output interface, universal definition + + -, in the connection of 2pin left positive right negative light bar interface, directly plug the middle 2, 3 pin can be, 1, 4 pin empty.

Specifications:

【Power supply operating conditions】 input: support 10-28V DC input

【Output voltage】 below 88V auto-adaptation (minimum limit for the input voltage value, no buck)

【output current】 default 80mA, by shorting R22 R21 R18 R15 R24 resistors, you can increase the current, 80mA per resistor. maximum 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 6：Ground

【Output Interface Definition】: Positive and negative (++-) There are four parallel interfaces, the definition is the same.
