2.1.2.2 DC Input Port (J10) (Option)
The SSPA Chassis can also be configured with a DC Input Voltage power supply. The
DC Input Voltage can range from 42-60 VDC.
The bulkhead connectors at the rear panel enable a quick connection to the “+” and “-”
terminals via the supplied connector housings and lengths of 4AWG cable.
Figure 2-3
shows an outline drawing of the rear view of the 48VDC Input option.
2.1.2.3 DC Input with N+1 Redundant External Power Supply (J10) (Option)
The combination of a se12 VDC output, fully redundant power supply is an
excellent means of obtaining the ultimate system reliability. The power supply is an
N+1 redundant configuration, meaning that one extra power supply module is available
than is required to operate the SSPA. A failure of a single power supply module will
not take the amplifier off the air.
In addition, the power supply modules are removable from the front panel while in
operation. There is never a need to remove the power supply from the equipment bay.
Weighing only 9 lbs. (4 kg) and occupying only 1 rack unit of cabinet space, the
redundant power supply chassis is an excellent companion to the SSPA chassis.
Power connection to the SSPA is via quick-snap connectors to the input power
bulkhead at Port J10.
Each power supply has a single phase, universal AC input ranging from 90-264 VAC,
47-63 Hz and is power factor corrected to 0.99. Depending on the power requirements
of the SSPA, the power supply is configured with either 750W or 1200W hot-
swappable modules, each of which weigh approximately 5 lbs. (2.3 kg).

Power Supply.
