The microprocessor monitors various voltages, currents and temperatures within the
unit for a full fault analysis. The user also has the ability to select additional faults
related to the RF output level, an optional reflected RF power level and operating
temperature.
An internal attenuator allows up to 20.0 dB of attenuation to be applied to the RF
signal. Temperature compensation limits the amplifier’s output response from varying
significantly over the operating temperature. Also, the system contains input and
output sample ports.
1.2 Specifications
Refer to the specification sheet in Appendix E for complete specifications.
1.3 Equipment Supplied
The following equipment is supplied with each unit:
• SSPA Chassis RM (4 RU high)

1.7 Safety Considerations
Potential safety hazards exist unless proper precautions are observed when working
with this unit. To ensure safe operation, the user must follow the information, cautions
and warnings provided in this manual as well as the warning labels placed on the unit
itself.
1.7.1 High Voltage Hazards
High Voltage, for the purpose of this section, is any voltage in excess of 30V. Voltages
above this value can be hazardous and even lethal under certain circumstances. Care
should be taken when working with devices that operate at high voltage.
• All probes and tools that contact the equipment should
be properly insulated to prevent the operator from
coming in contact with the voltage.
• The work area should be secure and free from non-
essential items.
• Operators should never work alone on high voltage de-
vices. There should always be another person present in
the same work area to assist in the event of an emergency.
• Operators should be familiar with procedures to employ in the event of an
emergency, i.e., remove all power, CPR, etc.
• An AC powered unit will have 115 VAC or 230 VAC entering through the AC power
connector. Caution is required when working near this connector, the AC circuit
breaker, or the internal power supply.
1.7.2 High Current Hazards
Many high power devices are capable of producing large
surges of current. This is true at all voltages, but needs to
be emphasized for low voltage devices. Low voltage
devices provide security from high voltage hazards, but also
require higher current to provide the same power. High cur-
rent can cause severe injury from burns and explosion. The
following precautions should be taken on devices capable of
discharging high current:

12 201627 REV X 4 RU SSPA Chassis Operations Manual
• Remove all conductive personal items (rings, watches, medals, etc.)
• The work area should be secure and free of non-essential items.
• Wear safety glasses and protective clothing.
• Operators should never work alone on high risk devices. There should always be
another person present in the same area to assist in the event of an emergency.
• Operators should be familiar with procedures to employ in the event of an
emergency, i.e., remove all power, CPR, etc.
Large DC currents are generated to operate the RF Module inside of the enclosure.
EXTREME CAUTION IS REQUIRED WHEN THE ENCLOSURE IS OPEN AND THE
AMPLIFIER IS OPERATING. DO NOT TOUCH ANY OF THE CONNECTIONS ON
THE RF MODULES WHEN THE AMPLIFIER IS OPERATING. CURRENTS IN
EXCESS OF 60 AMPERES MAY EXIST ON ANY ONE CONNECTOR.
1.7.3 RF Transmission Hazards
RF transmissions at high power levels may cause eyesight damage and skin burns.
Prolonged exposure to high levels of RF energy has been linked to a variety of health
issues. Please use the following precautions with high levels of RF power.
• Always terminate the RF input and output connector
prior to applying prime AC input power.
• Never look directly into the RF output waveguide
• Maintain a suitable distance from the source of the
transmission such that the power density is below
recommended guidelines in ANSI/IEEE C95.1. The
power density specified in ANSI/IEEE C95.1-1992 is
10 mW/cm2. These requirements adhere to OSHA
Standard 1910.97.
• When a safe distance is not practical, RF shielding should be used to achieve the
recommended power density levels.
1.7.4 Electrical Discharge Hazards
An electric spark can not only create ESD reliability problems, it can also cause serious
safety hazards. The following precautions should be followed when there is a risk of
electrical discharge:
• Follow all ESD guidelines
• Remove all flammable material and solvents from the
area.
• All probes and tools that contact the equipment should
be properly insulated to prevent electrical discharge.
• The work area should be secure and free from non-
essential items.

4 RU SSPA Chassis Operations Manual 201627 REV X 13
• Operators should never work alone on hazardous equipment. There should always
be another person present in the same work area to assist in the event of an
emergency.
• Operators should be familiar with procedures to employ in the event of an
emergency, i.e., remove all power, CPR, etc.

off.

4 RU SSPA Chassis Operations Manual 201627 REV X 17
2.1.2 Rear Panel Features
Figure 2-2 shows an illustration of the rear panel view of a standard AC input Rack
Mount chassis. The rear panel features the prime power connection, a removable
Monitor & Control Card Assembly, removable fan assemblies, and the RF input and
output ports.
2.1.2.1 AC Input Port (J10)
The prime power connector, J10, provides universal AC input by using auto-sensing
power supplies. The AC input can operate over a range of 90-265 VAC, at 47 to 63 Hz.
The power supply is also power factor corrected, enabling the unit to achieve a power
factor greater than 0.93. An IEC 6100-3300 (F) connector is used for SSPAs with 110V
input power. A connecting cable is included with the amplifier.
The highest output levels, >70 W @ Ku-Band and >140 W @ C-Band, should be
powered only from a 180-265 VAC source. This will keep AC line currents to safe
operating levels for the internal EMI filter and associated circuitry. An IEC 4798-9000
(F) connector is used for SSPAs with 220V input power. A mating connector is
included with the amplifier. The prime power vs RF output power is summarized in the
specifications in Appendix E.

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 separate +12 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).
Figure 2-4 shows an outline drawing of an SSPA with a N+1 Redundant External
Power Supply.

The power supply chassis has a dual feed AC architecture.
Power module slots 0 & 1 are supplied via AC Feed 1 and
power module slots 2 & 3 are supplied via AC Feed 2.
The AC connections on the shelf are made via rear accessed
compression style terminal blocks. See Figure 2-5. Connect
the first line/hot to L1, the second line or neutral to L2/N and
the AC ground to GND. These terminal blocks will accept up
to a maximum of 10 AWG wire, and should be torqued to
6 in-lbs.
The power supply is connected to the SSPA via an alarm
cable, part number L205676-1, supplied with the unit. This
cable connects between the Alarm port of the power supply and the PS M&C Port
(J12) of the SSPA. See Figure 2-6.
Each power supply module has an alarm output. For logic reporting purposes, the
alarm outputs for power supply modules 1 and 2 are linked, as are those for power
supply modules 3 and 4. The power supply alarms are monitored by the SSPA Chassis
monitor and control system. This provides local and remote alarm reporting in the
event of a power supply module failure.
The module alarms are open-collector signals with a high impedance state = fault logic
level. Under normal operation, the alarm outputs are in an open collector logic low
state.
