3: Simple to use
4: stable performance
5: 26-55 inch universal type
 
 
parameter
Input voltage range: 10-26V DC
Output voltage range: 65-165V DC
Output current: 10MA-1000MA can be set
Size: 12*6cm (manual measurement) Net weight: 55g
 
The working voltage of the light bar must be any voltage between 65V-165. Can't be lower than 65V
It cannot be higher than 165V. The design limit working voltage of this product should not be higher than 165V. If this voltage is exceeded, the screen will be dark or the lamp tube 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, so you do not need to worry about the voltage measured when it is no-load.
Regarding the description of changing the resistance, not every light bar needs to change the resistance when going back. Go back and light it up first. If the brightness is too dark, you need to increase the current by shorting the resistance. It doesn't matter if it is connected to the resistance, please be aware of the maintenance colleagues!
 
 
Possible problems with correct lighting:
1. The brightness is not enough, and the screen is obviously darker than the original board. At this time, we should start from two aspects. First, after connecting the dimming feet, try to use the remote control to brighten the brightness and see if it can be solved. If it cannot be solved, test the actual (Note: The brightness of my product is the largest when the voltage is 0V, and the brightness is the darkest when the voltage is high.) If it is analog voltage mode, the voltage range is between 0V-5V or 0V-3.3V, if the voltage is always high The voltage cannot be lowered and this should be adjusted. If it is a PWM signal, the voltage is stable and is 3.3V. At this time, if it is adjusted to the brightest and still fails to meet the requirements, the second solution must be implemented. Second, adjust the resistance on the board and increase the current to meet the requirements.
