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
DC output overvoltage protection threshold
Range: 58.5 V DC-60.5 V DC

If an overvoltage occurs inside a
rectifier, the rectifier locks out.

If the external voltage is higher than 63
V for more than 500 ms, the rectifier
locks out.
