Specifications
DC output
protection
DC output overvoltage
protection threshold
58.5 V DC to 60.5 V DC
Rectifier Efficiency
R4850G2:
≥
96% (peak point)
≥
95% (230 V AC, 30–100% load)
Output power
R4850G2:
3000 W (input voltage: 176–290 V AC)
1250 W (The power linearly derates when
the voltage ranges from 85 V AC to 175 V
AC.)
Overvoltage protection
58.5 V DC to 60.5 V DC
If overvoltage occurs inside a rectifier due
to a fault, the rectifier experiences a
deadlock.
If the external voltage is greater than 63 V
DC for more than 500 ms, the rectifier
experiences a deadlock.
