AC input
protection
AC input overvoltage
protection threshold
Overvoltage protection is triggered when the single-phase AC
input voltage exceeds the AC input overvoltage protection
threshold (300 V AC by default).
AC input overvoltage
recovery threshold
When the voltage is restored to 290 V AC, the output resumes.
AC input undervoltage
protection threshold
Undervoltage protection is triggered when the input
single-phase voltage is lower than the AC undervoltage
protection threshold (85 V AC by default).
AC input undervoltage
recovery threshold
When the voltage is restored to 90 V AC, the output resumes.

Efficiency
R4850G1: maximum ≥ 96%
≥ 95% (230 V AC, 20%–90% load)
R4850N1: maximum ≥ 92.5%
≥ 91.5% (230 V AC, 35%–80% load)
Output power
R4850G1 3000 W (176 –300 V AC);
1200 W (85–175 V AC)
R4850N1 2900 W (176–300V AC);
1200 W (85–175 V AC)
Output soft start
The output voltage rises slowly during rectifier power-on. The
time for voltage rise is configurable.
Overvoltage protection
Protection range: 58.5–60.5 V DC (configurable on the SMU)
If overvoltage occurs due to an internal fault, the rectifier
locks out.
If the external voltage is greater than 63 V for more than
500 ms, the rectifier locks out.
