On-Line Battery
15
On-Line battery lets the UPS
operate during power failures
without switching, since the battery
is linked directly to the DC bus.

Battery cabinets
� In most cases the battery cabinets are external.
Nevertheless, internal hot-swap battery cabinets for low
capacities are available as well:
64/60 x 20AH/12V

64/60 x 20AH/12V
64/60 x 5AH/12V
Static Switch
Distributed Static Switch:
� In this case, each UPS module has got its own internal static
switch
� Outputs of all modules are linked together and are wired
directly to the load19
Static Switch (cont..)
Centralized Static Switch:
� When implementing centralized topology, outputs from all
modules are linked together to the “inverter” input of the static
switch module.
� There is one device that handles the inverter / bypass switching20

For even more power and extra redundancy,Power+ can be put in parallel
de-centralized configuration. This will enable a combination of both vertical
and horizontal redundancy!

Why do we use -48VDC in telecom equipment ?
• Positive voltages cause comparatively more corrosion inmetal than negative voltages.
• Negative voltages are safer for human body while doingTelecom activities.
• Lightning may cause positive voltages in the equipment• Lightning may cause positive voltages in the equipmentcircuitry. In that case, negative voltages (lack ofelectrons) neutralize positive charges and preventexcessive heat.
• Negative voltage is safer for long telephone line fortransmitting power trough it.
• The reason for electing -48V in reference to ground is toavoid the nasty galvanic effects in telephone cabling.+48V would have nastier effect on wet cabling.

� 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 during the operation of the
system. Therefore the Power system
becomes more reliable and smaller in
footprint

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
