1 Introduction
General The Galaxy Power System, model 4824, was developed by
Lucent Technologies to support -48 volt telecommunication
powering solutions in worldwide markets. GPS 4824 combines
100 ampere natural convection-cooled switch mode rectifiers,
microprocessor control technologies, battery disconnect/
reconnect options and a comprehensive line of fuse and circuit
breakerdc distribution options in a modular front-access design.
This modularity ensures easy access, simple installation, and fast
maintenance and allows the system to expand in capacity,
hardware and software features incrementally as power needs
grow.
The main emphasis of this manual is to provide a general product
description that will familiarize the user with the main
components of the system and provide an understanding of the
installation, operation and maintenance of the Galaxy Power
System.
Architecture The system operates from commercial power in either 200-240
Vac, three phase (DELTA) applications or 350-415 Vac three-
phase, four wire (WYE) applications over a frequency range of
47-63 hertz. It is designed for modular growth from a small 200
ampere capacity to a large 2400 ampere capacity using the same
system components for all system sizes. The GPS 4824 is
designed for a distributed architecture (see Figure 1-1), which
means that each system cabinet contains rectifiers, dc
distribution,andbattery connections.Powerisdelivered fromhe
rectifiers or batteries to load circuits terminated in the cabinet.

Lucent Technologies Galaxy Power System 4824
1 - 2 Introduction Issue 1 November 1996
Thus, the load is distributed across the power systems’ cabinets.
In this distributed architecture design, the initial cabinet shown
in Figure 1-2, is comprised of an AC circuit breaker box, two
rectifiers, the controller, DC distribution panels and battery
connection module. For larger systems, additional cabinets
accommodate up to three rectifiers as shown in Figure 1-3. Each
cabinet contains connecting bus bars, allowing current to be
shared with an adjacent cabinet and insuring a common voltage
reference for the rectifiers.One of the major advantages of the
distributed architecture is that it enables gradual, cost-effective
system growth. As the application requires increased capacity,
the system can be grown by adding another system cabinet. Each
cabinet has its own battery shunt. The system load current is the
difference between the sum of all rectifier currents and the sum
of all battery section currents. There is no system shunt, and
therefore, there is no need to anticipate your maximum growth
needs at the time of initial installation and invest in a system
shunt and external busthatmay or may not everbefully utilized.
It does, however, require a designated floor area be reserved for
growth.
The GPS 4824 may also be configured in a centralized
architecture as shown in Figure 1-4. Rectifiers, batteries, and
distribution are cabled to external bus bar connected to a single
system shunt. Each cabinet contains rectifiers and/or
distribution. Distribution returns are terminated at the external
discharge return bus. The J85500A-2 battery plant is an example
of this architecture. This architecture requires a significant
amount of engineering and capacity planning, but growth is not
constrained to designated floor space.
Applications With2400amperecapacity,distributionflexibilityanduniversal
ac input capability, the GPS 4824 supports switching,
transmission, and wireless -48 volt power system applications
ranging from central office to the environmentally controlled
remote site (hut and vault).

System
Overview A basic block diagram of the Galaxy Power System is shown in
Figure 2-1. It illustrates the arrangement and interconnections of
the system components from the ac input to the dc output. The
power system accepts alternating current from the commercial
utility or a standby ac power source and rectifies it to produce dc
power for the using equipment. The system’s control and alarm
functions interact with the rectifiers and the office. In addition,
the system provides overcurrent protection, charge, discharge,
and distribution facilities. Battery reserve automatically
provides a source of dc power if the commercial or standby ac
fails. Battery reserve can be engineered to supply dc power for a
specific period of time. In normal practice, battery capacity is
sized to provide 3 to 8 hours of reserve time.
AC Input: connects the commercial and/or standby ac power
sources to the rectifiers within the system and provides
overcurrent protection.
Rectifiers: convertan ac source voltageinto the dc voltage level
required to charge and float the batteries and to power the using
equipment.
Controller: provides the local and remote control, monitor and
diagnostic functions required to administer the power system.
Batteries: provide energy storage for an uninterrupted power
feed to the using equipment during loss of ac input or rectifier
failure.

All bus bars in the system are copper with a solder plate finish
and sized to support 800 ampere capacity per cabinet. Two bus
bars are mounted vertically along the back of the cabinet. The
negative charge bus is on the left side and the positive return bus
is on the right side. Rectifiers are cabled directly to these two
buses from the dc output connector on the top of each rectifier.
The battery connection module and the dc distribution panels
connect to these buses as well. The buses of adjoining cabinets
are linked together with intercabinet bus bars to allow current to
be shared with adjacent cabinets.

Issue 1 November 1996 Product Description 2 - 5
Each cabinet is equipped with a BLJ1 connector board mounted
on the cabinet door (see Figure 2-2). The purpose of the
connector board is to provide a single point of connection for
alarms in the cabinet. The connector boards in each cabinet are
interconnected back to the controller to communicate fuse and
circuitbreakeralarms, open battery string alarms,ac alarms,and
to connect the rectifier serial communications cable.
There is a red alarm lamp (see Figure 2-2) at the top of each
cabinet. This lamp is also connected to theBLJ1 and lights when
a rectifier fails, a dc circuit breaker trips or fuse operates, an ac
breaker trips, or an open battery string alarm exists in the
cabinet.
Next to the BLJ1 connector board is space for an optional 211C
voltage peripheral module to monitor the status of each battery
fuse and the battery string voltage, a 211F current module to
monitor load shunts or battery shunts, and a digital meter panel
to indicate the current of one or two battery strings in a cabinet.
See Figure 2-2 for module location.
Galaxy Front
Access Controller The Galaxy controller provides GPS 4824 with a wide range of control and monitoring features. The controller is equipped with
a Basic control circuit that provides basic operations and an
optional Intelligent control circuit to provide advanced local
and remote monitoring and data acquisition features. These
control circuits monitor each others status and issue appropriate
alarms in the event a failure occurs.
The control panel has an 8 line by 40 character LCD display, 12
LED status indicators, test jacks for system output voltage and
output current and keys for viewing various menus to configure
and monitor the power system. A Microsoft Windows™based
configuration program, called EasyView, is included with the
Intelligent controller to make configuration of advanced
functions very user friendly by using a point and click interface.
The controller menus and EasyView are available in both

The Galaxy Front Access Controller manual (167-792-110) is
furnished with every GPS 4824. Refer to this manual for
information regarding configuration and operation. Refer to the
Galaxy Peripheral Monitor manual (167-790-063) for additional
information regarding module operation.
570A Rectifier The basic building block of the GPS 4824 is the natural
convection-cooled, 100 ampere switch-mode rectifier, model
570A. This rectifies commercial 50 or 60 hertz, 3-phase ac
powerintohighly regulated and filtered-48volt dcoutputpower
for telecommunications equipment loads. Table 7-1 lists the
specifications of the 570A rectifier.
The 570A rectifier is designed specifically for applications
where natural cooling, high efficiency, light weight, and ease of
installation are important. The rectifiers use a 70-kilohertz
switching frequency to achieve a significant reduction in size
and weight over ferroresonant rectifiers. The rectifiers are
naturally cooled and maintain safe operating temperatures in a
range form 0° C to 40° C. Air baffles mounted between the
rectifiers create a cooling convection air flow.
A power factor correction circuit incorporated in the design
ensures a power factor of 98 percent or greater for loads above
50 percent of the full load rating. The 570A rectifier is CE
marked and UL recognized and complies with UL1950
(Information Technology Equipment) and EN60950
requirements.
The rectifiers are shipped separately from the cabinets for quick
and straightforward installation on site. Interconnections to ac
input, dc output, and control signals are via cable connections
that plug into therectifier where shown in Figure2-4.The cables
are shipped within the cabinet.
The rectifier identifies itself to the controller by transmitting it
type and serial number , and the controller then sets the output
voltage to a pre-established value. No settings or adjustment to
potentiometers are necessary. The installer must set the
rectifier’s ID using the ON/STBY switch, to allow the controller
to learn the rectifier’s physical location.
