Full-bridge high-power LED backlight board instructions
1) Power input voltage 12V-28V; boost ratio 1:7.5, 12V can be increased to 80V, 24V boost to 160V.
2) LED lamp current defaults to 248mA, which can be adjusted to 600mA through short on the board.
3) The total power output is limited to 40W or less.
4) Optimized working efficiency of transformer efficiency 85°C, 40°C temperature rise 30°C
5) In the reverse dimming mode, ADJ is the dimming port, the grounding is the brightest, and the high voltage is dimmed to the extinction.
6) ADJ is not allowed to hang, if it is not connected, it will be directly connected to the ground.
(1, the boot has a soft start and other protection, so the dimming port should be connected to the ground when not in use. It is not recommended to be unconnected. 2. The setting of the dimming port is 0~3v, 0v is the brightest, 2~2.5v is already very dark, and it is basically protected near 3v. At this time, output 0v)
7) According to the flag on the board, connect VCC, GND, EN (enable), ADJ dimming, a total of four input ports, the output selects the LED positive and negative output ports.
Package include:
1 * 10-65 inch LED LCD TV universal boost constant current board
