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

� Less usage of space and storage
