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: Highest efficiency: ≥ 96%

≥ 95% (220 V AC, 40%-100% load)
R4815N1: Highest efficiency: ≥ 94%

≥ 93% (220 V AC, 30%-100% load)
 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.
