    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.

    (6.4) Communication between Rectifier/Solar Module & Monitoring Module

    CAN-bus communication mode is adopted between the rectifier/solar module and the monitoring module. Remote software version upgrade is supported, and the address of the module can be set through the address board. When AC input disconnects, the module needs to communicate with the host.
    Isolation design is employed for CAN interface in the rectifier module. The power supply of CAN is +5VDC, which is provided by the rectifier/solar module internally.
    The main monitoring information of the rectifier/solar module is as below:
    1) Voltage regulation and current regulation functions: meeting the requirements of floating charging battery and voltage regulation;
    2) Single module control of startup and shutdown;
    3) Protection and Alarm Information Feedback:
    • Mains fault: mains fault (AC input over-voltage/under-voltage);
    • Module protection: temperature pre-alarm;
    • Module fault: fan fault, over temperature shutdown or no output caused by the module internally; (the module is in the state of dormancy and shutdown, and the mains failure is not reported to the module).
