Modular N+1 Phase Combined System
System Prime Input Power
Proprietary adaptive bias techniques are utilized to achieve
an aggressive balance between RF output power and mini-
mized DC input power.
Prime power may be introduced into a terminal block at the
top of the cabinet. Electrical conduit is routed between the
terminal block and a 5RU boxed assembly, the AC Distribu-
tion/Circuit Breaker Panel, which houses a separate toggle
switch circuit breaker for each power supply module in the
system. Additional circuit breakers are available for auxiliary
equipment mounted in the cabinet.
System prime input power is achieved with an array of mod-
ular (hot-swap) power supply chassis. Power is distributed
from the power supplies to the SSPA modules via a bus rail
assembly.
Each of the power supply modules has its own single
phase, 180-264 VAC input. This makes it very convenient
to parallel the AC inputs of two modules and connect the
array to a three phase AC input source.
The power supply chassis is configured as a n+1 redun-
dant, hot swappable power supply. In the event of a power
supply module failure, the amplifier system will not fail. The
failed module can be changed without ever taking the HPA
out of service. The microwave amplifier architecture is also
designed for maximum soft fail redundancy.
Prime system AC Input Power specifications are shown on
pages 6-8 for various PowerMAX power levels and configu-
rations.
