LCD backlit power supply Q and A: Question One: Why is the output voltage lower than the nominal voltage? Answer One: This may be due to excessive load or insufficient power supply. Question Two: Why is there no negative voltage output or the output is too low? Answer Two: Negative voltage cannot be used alone. When using negative voltage, the same load must be applied to the positive voltage terminal.. Package List: 2 x Step Up Down Module Note:
