SYSTEM 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™ 802NLDB (208V Input Power/Distribution and Power Only Bays), 802NLEB
(480V Input Power/Distribution and Power Only Bays), and 802NL-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 consists 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-Control-Alarm (MCA) assembly. This panel in
the Primary Power Only Bay also houses the optional LMS Main CPU circuit card of
the integrated LMS Monitoring System. In a Secondary Power Only 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 Only 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 Only Bay is to be equipped with optional LMS I/O circuit cards, it must also be
equipped with an LMS Expansion CPU circuit card.)
Distribution Only Bays
The system consists of one (1) to eight (8) Distribution Only Bays.
Each Distribution Only Bay provides four (4) distribution buses.
