2.4 Working Principles
Figure 2-3 shows the conceptual diagram.AC power enters rectifiers through theAC power
distribution unit (PDU). The rectifiers convert the AC 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 the AC
power is absent, rectifiers stop working and batteries start to power loads. After theAC 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. The SMU monitors and regulates the temperature control unit based on the temperature
