| AC input protection |
AC input overvoltage protection threshold |
> 300 V AC |
| AC input overvoltage recovery threshold |
When the voltage is restored to 290 V AC, the output resumes. |
| AC input undervoltage protection threshold |
< 85 V AC |
| AC input undervoltage recovery threshold |
When the voltage is restored to 90 V AC, the output resumes. |
| DC output protection |
