| 18 | Time Lapse Drift | Long-term variation of output voltage over time |
| 19 | Rise and Fall Time | Time for output voltage to rise from 10% to 90% when input power is applied, and time to fall from 90% to 10% when input power is removed |
| 20 | Hold-Up Time | Duration the output voltage remains within regulation after input is removed |
| 21 | Instantaneous Interruption Compensation | The duration of input interruption during which the output voltage remains within the regulation accuracy when the load current is varied |
