2. UNIT OVERVIEW
The 86431 Power Unit provides the interface between the customer-supplied
station battery and a JungleMUX node.
The unit’s input voltage requirement can
be 24, 48 or 130 VDC depending on the unit option (refer to
Section 8: Ordering
Information
for more information).
The unit provides power supply to the shelf’s
5 VDC power bus.
Normally, two Power Units are paralleled on the same shelf to provide
redundancy in the case of a single Power Unit failure. If necessary, an additional
(third) Power Unit can be installed in the shelf.
The power buses of multiple shelves belonging to the same JungleMUX node
can be paralleled (refer to the 86430 Equipment Shelf TPIM). It is strongly
recommended that no more than six Power Units be paralleled.
The old-generation (B)86431-0X Power Units can sustain a maximum load of
18 W while the new-generation B86431-4X Power Units can sustain a maximum
load of 30 W on permanent basis. The (B)86431-0X and B86431-4X units are
compatible and can be paralleled along the same power bus.
