SYSTEM OVERVIEW
Description: -48V DC @ up to 16,800 amperes Power System.
This power system is designed to power a load while charging a positive grounded
battery. This power system is capable of operating in a batteryless installation or off
battery for maintenance purposes. This power system is designed for operation with the
positive output grounded.
The N
ETSURE™ 801NLDB (208V Input Power Bay), 801NLEB (380V/480V Input Power
Bay), and 801
NL-B (Distribution Bay) DC Power System is a complete integrated power
system containing rectifiers, intelligent control, metering, monitoring, and distribution.
This power system consists of the following components.
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
