5.6.4 Connecting the Auxiliary DC Power Output
The PMU can provide an auxiliary DC output from the auxiliary power
supply board. This board is available with an output of 13.65VDC,
27.3VDC, or 54.6VDC (depending on the model), and is current limited to
3A, 1.5A or 750mA respectively. This power supply is permanently on as
soon as the base station has finished powering up, and is available on the
auxiliary output connector on the rear panel.
You can connect multiple auxiliary power supply boards in parallel for
redundancy purposes, or to provide an output greater than 40W. Although
no active current sharing is used, auxiliary boards connected in parallel will
current-share before reaching their power limit. The failure (or switching
off) of one auxiliary board will not load any other paralleled auxiliary
boards in the circuit.
Auxiliary DC Power
Output Cabling
Network elements are supplied with a connector, as shown in Figure 5.10.
You can use this to connect the PMU’s auxiliary DC power output to
another device (refer to “PMU Auxiliary DC Output” on page 109 for the
pin allocations).
Contact your regional Tait office for details on the full range of wiring kits
available.
