  • 44. DC power system Why do we use -48VDC in telecom equipment ? • Positive voltages cause comparatively more corrosion in metal than negative voltages. • Negative voltages are safer for human body while doing Telecom activities. • Lightning may cause positive voltages in the equipment circuitry. In that case, negative voltages (lack of electrons) neutralize positive charges and prevent excessive heat. • Negative voltage is safer for long telephone line for transmitting power trough it. • The reason for electing -48V in reference to ground is to avoid the nasty galvanic effects in telephone cabling. +48V would have nastier effect on wet cabling.
  • 45. DC power system User friendly: -Light weight: 1,2kg/ module -Hot swapped system controller -USB or TCP/IP+USB communication Safety: -Option to connect 2 external LVD (Low voltage disconnect) contactors up to 1600A. Efficiency: -LLC tech to achieve efficiency 96%. -Input PF=0.998, THD for input voltage lower than 5% Standard & Maximize system capacity: -19” 1U subrack that can house up to 3 hot-plugged rectifiers, or 2 rects + controller and an LVD device. -Reach 1266A with height of 13U ((38 rectiers + controller)).
  • 46. DC power system High efficiency Power systems up to 95%-96% - Reduction in energy costs Parallel 1UDC rectifiers are lower in cost than high capacity single rectifiers- Reduction in Price A larger quantity of rectifiers creates singularity system. during Therefore the the operation Power of the system becomes more reliable and smaller in footprint
  • 47. DC power system Many new standards and industry goals are lead by the goal to save energy and reduce greenhouse gase emmissions. The 1UDC modules of Gamatronic increase energy savings The product is more environmental friendly Lowers cooling expenses Lowers heat dissipation Less usage of space and storage Lower generator over sizing (~1 to 1.2) Less pollution and fuel consumption
