Overvoltage protection is performed when the
single-phase AC input voltage exceeds the AC input
overvoltage protection threshold (300 V AC by
default).
When the voltage is restored to 290 V AC, the
output resumes.
Undervoltage protection is performed when the
single-phase AC input voltage is below the AC input
undervoltage protection threshold (80 V AC by
default).
When the voltage is restored to 85 V AC, the output
resumes.

R4815G1: 870 W (input voltage range: 176-300 V
AC) 435 W (input voltage range: 85-175 V AC,
linearly derated)
R4815N1: 1000 W (input voltage range: 176-300 V
AC) 470 W (input voltage range: 85-175 V AC,
linearly derated)
At the moment when the rectifier is powered on, the
output voltage rises slowly.
-58.5 V DC to -60.5 V DC
1. If the overvoltage occurs inside the rectifier due
to a fault, the rectifier experiences a latch-off.
2. If the output voltage is higher than -63 V DC and
lasts for more than 500 ms, the rectifier
experiences a latch-off.
