Communication
Output voltage can be adjusted through communication interfaces:
PMBus, CAN bus or Modbus. Please refer to chapter 6 for detailed
information.

shown in Figure 5-4.
D.Relationship between output current and external DC source I
shown in Figure 5-5.
E.Covered by over temperature protection, auto de-rating function
works under operation either in PC mode or under control by
communication protocol.
