1.4 Working Principles
Figure 1-5 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 theAC
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
measured by the temperature sensor to ensure the normal operating temperature for the
cabinet.

Class C environments refer to sea environments or outdoor land environments (with simple shielding
measures) near pollution sources. If a site is near a pollution source, it is at most 3.7 km away from salt
water, such as the sea and salt lakes, 3 km away from heavy pollution sources, such as smelteries, coal
mines, and thermal power plants, 2 km away from medium pollution sources, such as chemical, rubber,
and galvanization industries, and 1 km away from light pollution sources, such as packing houses,
tanneries, and boiler rooms.
