Precautions
The working voltage of the light bar must be any voltage between 60V-165. It cannot be lower than 60v; the design limit working voltage condition of this product should not be higher than 165v. If the voltage exceeds this voltage, the screen will be dark or the lamp will flicker.
This product is only constant current, not constant voltage, the voltage will be automatically adjusted to the corresponding voltage according to the demand voltage of the light bar;
There is no problem with the quality and performance of this product, and it may not be able to light up for modification, because the parameters of the modified product are unknown. Voltage, power supply, connection, structure, etc. may cause mismatch.
Possible problems with correct lighting
Option I:
After connecting the dimming foot, try to use the remote control to adjust the brightness to try to see if it can be solved. If it can’t be solved, test the voltage of the actual pin. (Note: The brightness of my product is the largest when the voltage is high, and the brightness is the darkest when the voltage is high. ). If it is an analog voltage mode, the voltage range is between oV-5v or 0V-3.3v. If the voltage is always high and cannot be reduced, this should be adjusted; if it is a PwM signal, the voltage is stable at 3.3V.
Option II:
Adjust the resistance on the board to increase the current to meet the requirements.
