ODU -48VDC Power Cable

The typical configuration for powering the ODU consists of:

  • ODU mounted outdoors, on roof, with maximum of 4A required at -48VDC
  • outdoor power cable, two conductors, 12AWG, rated for outdoor use (e.g. 250-ft roll of 12/3 SJTW cable)
  • ODU Circular Connector
  • Lightning surge protector mounted on a barrier terminal block in a weather tight box on the roof.
  • One power supply for ODU, Mean Well SP-200-48, 110VAC input, -48VDC output, rated 4.2A or 200W

Disassemble the connector by unscrewing the small screw shown in Figure 1 with appropriate Allen wrench.

The cable wires have to be soldered to the connector as shown in figures 2.

ODU Power Connector assembly is shown in figure 3. Once assembled and attached to the ODU, the connector has to be weatherproofed (as suggested on Page 51 of the NEC Installation Manual for Base Station (IMN:BS)).

The other end of the cable is attached to the Mean Well power supply as shown in Figure 4 (note that grounding should wire should not be used if the power supply and 110V is not available on the roof)
