1 Introduction
GPS 4812/24
Overview Lineage Power developed the Galaxy Power System (GPS) 4812/24 to
support -48 volt telecommunications powering solutions in worldwide
markets. The GPS 4812/24 combines 55-ampere and 110-ampere,
fan-cooled, switchmode rectifiers, microprocessor control technologies,
battery and load disconnect/reconnect options, and a comprehensive
line of fuse and circuit breaker dc distribution options in a modular
front-access design. This modularity ensures easy access, simplified
installation and maintenance, and allows the system to expand in
capacity and features as power needs grow.
With 7,040-ampere maximum capacity, distribution flexibility, and
universal ac input capability, the GPS 4812/24 supports switching,
transmission, and wireless applications in central office locations and
environmentally controlled remote sites (huts or vaults).
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 to provide guidelines for the basic maintenance of this
Galaxy Power System.
Note Prior to Issue 6 of this manual, the GPS 4812/24 cabinet had a metal
door and the Galaxy Vector Controller consisted of a BIC3 board. For
information on these systems, see Issue 5 of this manual.
