CA-299 26”-55″inch LED LCD backlight TV constant current inverter PCBA circuit board Led universal driver board
size: length = 8.5cm, width = 5.8cm, height = 1.2cm
Uses: 24-55-inch LED-backlit LCD devices (monitors, TVs, advertising machines, etc.)
Power Supply VCC: 19-45C DC
Output voltage: 55-170v
The default current is 200mA
The current can be self-adjusted, the board presets parameters, and can be adjusted as needed.
To ensure the reliability of the product,
please ensure that the board works within the technical parameters.
1, constant current output, the default current is 200MA, this value is constant output,
will not change greatly with time or power supply voltage fluctuations.
That is: with 19V power supply, the output voltage of 55V is 200MA, the use of 38V power supply,
the output current is the same 200MA.
2, the voltage automatically adapt: the design of the output range of 55-170V, as long as
the access to the light bar is within this range are automatically adapted, without human intervention.
3 free and quick current setting, the board is preset with the relevant current settings of
the solder joints and marked with a good value. The user can quickly change the output current according to actual needs.
