1 Introduction
GPS 4812
Overview Lucent Technologies developed the Galaxy Power System (GPS) 4812
to support -48 volt telecommunications powering solutions in
worldwide markets. The GPS 4812 combines 50-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 1200-ampere maximum capacity, distribution flexibility, and
universal ac input capability, the GPS 4812 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.
