801
5,800 watt rectifiers from Emerson
Network Power provide up to 110 amps
each. With 24 units per bay, these
rectifiers provide up to a 2,640 amp
output in a 24.375" x 30" footprint.
Description
The modular NetSure™ 801 power system
with 5800 watt rectifiers provides up
to 16,800 amps of power for -48 volt
systems. The basic components of the
system include 2640 amp power bays
which house the rectifiers and MCA
chassis, and 6000 amp distribution
bays. The cabled architecture allows the
placement of the bays anywhere the user
desires without regard to any specific
order. This also makes it more user friendly
in applications where existing obstacles,
such as support columns, need to be
accommodated. The total plant size is
defined by the maximum capacity of the
Main Battery Termination Bars (MBTB).
™
The NetSure
a powerful, microprocessor-based meter,
control and alarm system capable of
monitoring and controlling up to 168
rectifiers. The MCA provides a 4 line,
801 power system contains
40-character alphanumeric display, which
can be activated at the touch of a keypad.
Each rectifier bay can accommodate up
to 24 plug’n’play rectifiers, which are
controlled by the MCA. Additional bays can
be added as load requirements increase.
™
The NetSure
6000 amp modular distribution bays.
Each bay can be configured with up to
70 positions of fuses and circuit breakers
from 1-800 amps. Multiple bays may be
used to support load levels in excess of
16,800 amps. Contact an Emerson
application expert at 1-800-800-1280.

Modules & Options
Distribution Bay with Fuses
and Breakers Installed
AC Input
Two types of AC input are offered: dual
feed or twin feed. With the dual feed
option, two sources of AC are brought
into the termination panels. The AC is
internally distributed to the individual
rectifiers by 12 on-board circuit breakers
and the rectifiers are divided evenly
between sources. With the twin feed
option, each pair of rectifiers is sourced
separately from a customer provided
PDSC. This enables existing AC infrastructure to be used for 200 amp
rectifiers. If individual rectifier feeds are
required, simply remove the factoryinstalled jumpers. Conduit sizes up
to 2" can be accommodated.
Distribution
The NetSure
modular. There are a total of 48 distribution positions for GJ type circuit breakers
as well as an optional 24-position bullet
nose panel. In addition to E-Trip and E/M
Circuit breakers from 1 to 800 amps, the
system will accommodate TPS/TLS and
TPL fuses ranging from 1 to 800 amps.
Each GJ circuit breaker and TPL fuse is
individually monitored.
The system can also be expanded with
additional 6000 amp bays that do not
need to be adjacent to each other. The
only bay-to-bay connection required is
the CAN bus control cable. The power
feeds are cabled from the MBTBs.
Distribution device options include 1 to 250
amp plug-in circuit breakers, 3 to 100 amp
TPS/TLS-style fuses in plug-in holders, 100
to 800 amp GJ/218-style circuit breakers
and 70 to 800 amp TPL-style fuses.

Emerson Network Power —
nationwide service organization.
Monitoring/Control
The MCA provides a single point of
adjustment for such features as float
voltage, test/equalize voltage, high
voltage shut-down and current limit for
all rectifiers in the entire power system.
The MCA provides local indicators and
the ability to transmit various alarm
conditions, system measurements and
system settings. All measurements and
adjustments can be performed locally via
the alphanumeric display on the front of
the MCA panel or remotely using the
optional LMS1000 monitor.

ability to transmit various alarm conditions
such as rectifier failure, high voltage

R48-5800 Rectifier
Rectifier
The modular R48-5800 is a high frequency
rectifier designed with the latest patented
DSP (Digital Signaling Processing)
switch-mode technology. DSP reduces
cost by optimizing system operation and
requiring fewer components. System
configuration is easily accomplished with
these plug’n’play rectifiers. Rectifiers are
simply added to an existing rectifier bay or
newly added power bay to increase
capacity — no adjustments or setup are
™
required. NetSure
801 power systems
accommodate up to 264 rectifiers, which
provide load power and battery recharge
current. The rectifiers are monitored and
controlled by the MCA. The R48-5800
rectifiers enable the power plant to easily
grow to meet specific application needs.
Rectifier Bay

The NetSure
801 rectifiers are housed in
modular power bays that accommodate
24 rectifiers each. The rectifier bays are 7'
high x 24.375" wide x 30" deep. System
capacity can be easily expanded with
additional bays.
