1. Introduction
GPS4827
ABB Power developed the Galaxy Power System GPS 4827 to support - 48 volt telecommunications
powering solutions in worldwide markets. The GPS 4827 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 as power needs grow.
With 1,800 - ampere maximum capacity, distribution flexibility, and universal ac input capability, the
GPS 4827 supports switching, transmission, and wireless applications in central office locations and
environmentally controlled remote sites (huts or vaults).
