AC input
overvoltage recovery
threshold
When the voltage is restored to 290 V AC, the output resumes.
AC input

DC output
overvoltage
protection threshold
–58.5 V DC to –60.5 V DC
1.
If overvoltage occurs inside the rectifier, the rectifier locks
out.
2.
If the external voltage is greater than -63 V for more than 500
ms, the rectifier locks out.
