The rectifier power factor is 0.99.
2.4 Working Principles
Figure 2-2 shows the conceptual diagram.AC power enters rectifiers through the AC power
distribution unit (PDU). The rectifiers convert theAC power input into -48 V DC power
output, which is directed by the DC PDU to DC loads along different routes.
When theAC power is normal, rectifiers power DC loads and charge batteries. When theAC
power is absent, rectifiers stop working and batteries start to power loads. After the AC power
resumes, rectifiers power DC loads and charge batteries again.
The SMU monitors the operating status of each component in the power system in real time
and performs appropriate intelligent control. When detecting a fault, the SMU generates an
alarm.
