C3-Type DC PDU

C3-Type DC PDU

This topic provides the appearance and main performance specifications of the C3-type DC PDU, and describes the power distribution principle of the PDU.

Appearance

Figure 6-8 and Figure 6-9 show the appearance of the C3-type DC PDU.

Figure 6-8  Appearance of the C3-type DC PDU (with cover)

Figure 6-9  Appearance of the C3-type DC PDU (without cover)

Function

The C3-Type DC PDU provides the following functions:

  • Short-circuit protection and overload protection
  • The functions such as over-voltage protection, lightning proof, and filter are not provided.

Power Distribution Principle

Figure 6-10 shows the power distribution principle of the C3-Type DC PDU.

Input Terminal

Figure 6-11 shows the input terminals of the C3-type DC PDU.

Figure 6-11  Input terminals of the C3-type DC PDU

The C3-type DC PDU supports two -48 V DC/-60 V DC inputs. The connections of the input terminals are as follows:

  • RTN1 (+) connects to RTN of the first channel DC power supply.
  • NEG1 (-) connects to NEG of the first channel DC power supply.
  • PGND connects to the ground cable.
  • RTN2 (+) connects to RTN of the second channel DC power supply.
  • NEG2 (-) connects to NEG of the second channel DC power supply.
NOTE:

By default, the two channels of input power are provided by different power sources. To use the same power source to provide two channels of input power, connect a jumper to the terminal of each channel, as shown in Figure 6-10.

Output Terminal

Figure 6-12 shows the output terminals of the C3-type DC PDU.
