Power Bays
The system consists of one (1) Primary Power Bay and up to six (6) Secondary Power Bays.
Each Power Bay can be equipped with up to twenty-four (24) Rectifier Modules.
Each Power Bay contains a Monitor and Control
Panel. In the Primary Power Bay, this panel
houses the Meter-Control-Alarm (MCA)
assembly. This panel in the Primary Power Bay
also houses the optional LMS Main CPU circuit
card of the integrated LMS Monitoring System. In
a Secondary Power Bay, this panel can be
equipped with an optional LMS Expansion CPU
circuit card. (The optional LMS Monitoring
System provides a higher level of monitoring and
controlling capabilities to the power system.)
The Monitor and Control Panel in both Primary
and Secondary Power Bays contain a seven-slot
card cage to house MCA alarm relay circuit cards,
MCA input/output (I/O) circuit cards, and
optional LMS I/O circuit cards. (If a Secondary
Power Bay is to be equipped with optional LMS
I/O circuit cards, it must also be equipped with
the LMS Expansion CPU circuit card.)
Distribution Bays
The system consists of one (1) to eight (8)
Distribution Bays.
Each Distribution Bay provides four (4)
distribution buses.
Each distribution bus accepts a choice of
218-type circuit breakers and TPL-type fuses.
A Distribution Bay may also be equipped with an
optional distribution panel which accepts a choice
of TPS/TLS-type fuseholders or Bullet Nose-type
circuit breakers.
Rectifier Modules
The Rectifier Modules provide load power,
battery float current, and battery recharge
current during normal operating conditions.
