DC Power Cable (Cabinet)

DC Power Cable (Cabinet)

The DC power cable is used to transmit the DC power to loads and enable the loads to work in the normal state.

Application

The DC power cable (cabinet) connects the power port of the device to the external power supply. It is connected as follows:

  • One end of the DC power cable is connected to the output port of the DC power supply.
  • The other end of the DC power cable is connected to the input port on the DC PDU of the device.
NOTE:

The black cable is the -48 V return ground cable connected to the RTN(+) terminal of the DC power board. The blue cable is the -48 V power cable connected to the NEG(-) terminal of the DC power board.

Appearance and Structure

Figure 5-1 and Figure 5-2 show the appearances of a -48 V return ground cable and a -48 V power cable.

Figure 5-2  Appearance of a -48 V power cable

Technical Specifications

The technical specifications of a -48 V return ground cable and a -48 V power cable are the same, as listed in Table 5-1.

Table 5-1  Technical specifications of a -48 V return ground cable and a -48 V power cable

Specification

Description

Cable type

Electrical cable

Color

Black (-48 V return ground cable); blue (-48 V power cable)

Maximum current

110 A

DC resistance of the inner conductor

0.78 ohms/km

Cross-sectional area of the conductor

25 mm2 or 16 mm2
NOTE:
The diameter and length of the DC power cable affect the power supply of the device.
  • The DC power line, whose length is shorter than 20 m and whose cross-sectional area is 16 mm2, can meet the device voltage requirement.
  • The DC power line, whose length is longer than 20 m but shorter than 32 m must have a cross-sectional area of 25 mm2 to meet the device voltage requirement.
