Rectifier
Current sharing
Rectifiers can work in parallel and share the current. The unblanceness is
better than ±3% rated current. Test current range: 10% ~ 100% rated current
Derate by input (45°C)
The rectifier can output max. power of 5,800W with input voltage of 304Vac ~
530Vac.
The output power will drop to 50% rated power when the input volatage fall to
304Vac ~ 260Vac
