1. Description:

This is CA-266S 32-65inch LED TV backlight board Led universal inverter 80-480mA Constant current board.

2. Parameters:

1>. Power supply condition input: support 10-28V DC input

2>. Output voltage: automatic adaptation below 88V (minimum limit for input voltage, no depressurization)
3>. Output current: the default 80mA. Increases the current by shorting the R22 R21 R18 R15 R24 resistor. Each resistor 80mA. Highest 480mA.
4>. Suitable for light bar: large size 32inch -65 inch (maximum voltage 88V)
5>. 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
6>. Output interface definition: It is a four (++--) parallel interface. Definitions are all the same.

3. Function:

1>. With protection.
2>. Output voltage: below 88V automatic.
3>. It is convenient to change the current. There are 6 of 1206 resistors on the motherboard. One resistor represents 80mA, and the highest 6 resistance fully connected to 480mA.
4>. The default is only connected 1 R13 resistors, the output current is 80mA. It won’t burn the lamp strip. If it's too dark, blinking, or flashing, please try to increase the current.
5>. No load will not burn the board (in the case of no load or lamp bar, the output voltage will fall to the input voltage size, or the load voltage is higher than 88V that will also reduce to the input voltage value).
6>. There are 4 output interface, the common definition for ++--. When connecting the left positive and right negative lights of the 2pin, the 2 and 3 needles can be inserted directly into the center, and the 1 and the 4 needles are empty.

4. Using attention:

Please don't touch the ADJ pin during the test!
