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

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).
