Description: The LED Strip Voltage must be between 60V-165V. Not less than 60V, if less than 60V, you can choose our other item..Not higher than 165V, the product design conditions shall not exceed the maximum working voltage of 165V.If the voltage exceeds, the screen will appear dark or flashing lamp and so on. This product is only constant, not constant voltage, the voltage will automatically adjust to the appropriate voltage according to the led strip need, so you do not worry about in no-load voltage condition measuring how much voltage is. You may meet the problems after correct lighting: The brightness is not enough, the screen is significantly darker than the original's . Now you need to do the two things: First, attempt to use the remote control after connected to the transfer barefoot to try brightness, if not resolved,test the actual pin voltage (Note: it will be the greatest brightness in 0V, the brightness will be the darkest in greatest Voltage), if it is an analog voltage mode voltage range is between 0V-5V or 0V-3.3V, if the voltage has been in hight condition all the time andcan not be reduced, now you need to adjust it . the voltage is 3.3V if it is PWM signal, it still can be up to request if adjust to the greatest brightness at this time ,you need to do second program Second, adjusting the resistance, increases the current to meet the requirements. Specifications: Model: CA-288 Used for: 26inch-55inch LED TV Input Voltage: 19-45V DC Output Voltage: 60-165V DC Output current: 200mA (Constant) Size: 120x60mm/4.72x2.36" Quantity: 1 Pc Note: Please allow 1-3mm error due to manual measurement. pls make sure you do not mind before you bid Due to the difference between different monitors, the picture may not reflect the actual color of the item.
