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

product description
Uses: 24-55-inch LED-backlit LCD devices (monitors, TVs, advertising machines, etc.)

Technical Parameters:
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.
Features:
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.
