Universal LED LCD TV Backlight Constant Current Board inverter
Output voltage: The voltage requires the backlight of the LCD screen at 20-55v or less,the specific output power depends on the screen (matches the output power automatically).
Output current: About 240mA
Working temperature: -10 ~ +50℃
Storage temperature:-20 ~ +70℃
Screen size:15-24inch LCD Screen(port matched is ok))
Light bar port:1 PH2.0 - 4PIN connector
1PH2.0 -2PIN connector
Notice: Supply with one power supply line,do not supply output line.
[General LED constant current board modification instructions]
1. Connect the power, ground, and switch signals required by the boost board to the universal LED boost board.
VCC supply, ON switch signal, ADJ brightness control, GND ground
Tip: The same connection method as the LCD high-pressure plate
2.Use a multimeter to measure how many lines are connected for the LED light bar power supply,which are the lines required;How many negative lines,which are the respective one.No matter how many lines, only the positive and negative points, people who understand the technology should not have to measure it, see the light bar can understand the definition.
Example: The definition of 10P interface is 3- 4+ 3-
Tip: The power supply for the LED strips is the same, all connected together, the number of strips represent the number of series circuits.
Example: 3- 4+ 3- (6 series circuits)
6P*2, 7P*1, 10P*2, 12P*2
Not all ports are soldered on. We have pre-installed one or more. See the description above for details.
· The LED connection must pay attention to the interface definition (positive and negative) points, positive input power supply, do not reverse or wrong.
· Individual DIY must consider the technical ability first,then decide purchase it. If the connection is improper, please bear the consequences. Please kindly understand!
· It is recommended to find professional technicians! it is not worth the candle if burning other stuff.
