Q&A:
Question 1: Why is the output voltage le than the nominal voltage
Answer 1: This may be because the load is too large, or the power supply is too small
Question 2: Why is there no negative voltage output or the output is too low?
Answer 2: Negative voltage cannot be used alone. When using negative voltage, the same load must be added to the positive voltage terminal.
