SYSTEM OVERVIEW
Description: -48V DC @ up to 10,000 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 NetSure™ 802
NLDB (208V Input Power/Distribution and Power Only Bays), 802NLEB
(480V Input Power/Distribution and Power Only Bays), and 802
NL-B (Distribution Only
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/Distribution Bays
The system can consist of one (1) Primary Power/Distribution Bay and up to nine (9)
Secondary Power/Distribution Bays.
Each Power/Distribution Bay can be equipped with up to ten (10) Rectifiers and
provides distribution. Distribution is divided into two buses which accept a choice of
fuse and circuit breaker types and sizes.
Each Power/Distribution Bay contains a Monitor and Control Panel. In the Primary
Power/Distribution Bay, this panel houses the Meter-Control-Alarm (MCA) assembly.
This panel in the Primary Power/Distribution Bay also houses the optional LMS Main
CPU circuit card of the integrated LMS Monitoring System. In a Secondary
Power/Distribution 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/Distribution 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/Distribution Bay is
to be equipped with optional LMS I/O
circuit cards, it must also be
equipped with an LMS Expansion
CPU circuit card.)
Power Only Bays
The system can consist of one (1)
Primary Power Only Bay and up to
nine (9) Secondary Power Only
Bays.
Each Power Only Bay can be
equipped with up to ten (10)
Rectifiers.
Each Power Only Bay contains
a Monitor and Control Panel. In
the Primary Power Only Bay,
this panel houses the Meter-
