4. Telecom Rectifier Working Principles
(1) Figure Conceptual Diagram shows the conceptual diagram. DC power enters solar module through the DC power distribution unit (PDU).
The solar module converts high-voltage into -48VDC. AC power enters rectifiers through the AC PDU.The rectifiers convert the AC power
input into -48VDC power output, which is directed by the DC PDU to DC loads along different routes.
(2) During normal operation, the solar module priority to the DC load and charging batteries. When the solar power is low, the AC power , rectifiers power DC loads and charge batteries. When both the AC and solar are absent, rectifiers and solar modules stop working and
batteries start to power loads. After the AC or solar power power resumes, rectifiers or solar module power DC loads and charge batteries again.
(3) The monitoring unit monitors the running state of each component of the telecom power supply system in real time, and carries out the corresponding intelligent control. When detecting a fault, the monitoring module generates an alarm.
