15. On-Line Battery
On-Line battery lets the UPS
operate during power failures
without switching, since the battery
is linked directly to the DC bus.
15
18. 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 5AH/12V

19. Static Switch
Distributed Static Switch:
19
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 load
20. 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 switching
20
22. System Controller
PC575 is the WEB interface board:
Network adaptor is a standard
feature of the System Controller
Remote control features cover all
possible options:
SNMP communication
Web interface
Emergency power off
(EPO)
SMS alarm notifications
(with optional WING
device)
Remote monitoring panel
The IP address can be configured on the
System Controller or through the network.

23. Redundancy
+
6 modules for 50k
N+1 redundant system
Two complete 50k units
for N+1 redundancy
The modular design of Power+ UPS provides a cost effective redundancy
with higher efficiency than conventional parallel UPS systems.

38. Parallel Connection
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!
Toady there are dozens
of 200, 300, and 400kVA
systems worldwide,
supporting most critical
applications.

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
