Power and Ground Interfaces
2.5.1
AC Power
The PCB-4000A derives its power from the SSPAs. Each SSPA provides a +24V signal line via
cables interconnecting the SSPAs to the
SSPA COM 1 | J2
and
SSPA COM 2 | J3
connectors
(Pin ‘R’ – see Table 2-3). These two signals are “diode OR’ed” to provide redundancy.
Although the PCCB will turn on and function with only one SSPA is powered on,
the system does not provide optimum output power unless both SSPAs are
powered on.
2.5.2
Ground Connector
A #10-32 stud is provided on the front panel of the PCCB for connecting a common
chassis ground among equipment.
