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.
