Interruptions to critical
business processes, whether
due to hardware faults, production
breakdowns, communications failures
or insufficient - or even non-existent
- protection against voltage
fluctuations, can have far reaching
consequences. After all, system
availability and the reliability
of IT infrastructure platforms
are decisive factors for the
efficiency and productivity
of company processes - and thus
equally for business success.
Miniaturization and the ever
greater performance of the hardware
components place new demands
on modern power management concepts.
The answer to this dilemma:
Power management with RimatriX5.
The demands with regard to redundancy,
scalability and maximum availability
are bundled into a single system.
Together, the solutions help
to reduce operating costs and
boost the availability of the
overall system. It is even possible
to retrofit new modules without
interrupting operation.
Particularly effective: The
"n+1" technology, which ensures
optimum redundancy and enhances
availability. Indeed, the Power
Modular Concept (PMC), with
its innovative distributed parallel
architecture (DPA), stands for
ultimate system availability.
The power management product
range for power distribution
in the data centre is based
on the consistent implementation
of plug-&-play expansion - with
no need to interrupt current
operations. Downtimes are avoided
and future operating costs are
lowered.

Power Modular Concept (PMC)
for power supply protection
PMC provides innovative protection
against power supply problems.
Through the combination of modularity
(scalability and redundancy)
and distributed parallel architecture
(DPA), it guarantees maximum
availability for critical applications.
Thanks to the modular DPA system
architecture, it is possible
to expand capacities and stored
energy times without interrupting
operation.
Single-phase UPS, power
range 1 - 6 kVA
- High-quality double-conversion
technology with optimum
sine-wave output voltage
- Battery expansion for
extended stored energy time
Intelligent battery management
monitors battery readiness
and guarantees system availability;
furthermore protection against
overcharging and exhaustive
discharge.
- Scope of delivery offers
software compatibility for
all standard operating systems
- System load reduced
by preventing continuous
server polling after shutdown
Three-phase UPS, power range
10 - 120 kVA per rack
- Performance/modularity/redundancy
PMC is a new three-phase
UPS concept offering modular
"n+1" redundancy on the
basis of double-conversion
technology. The modular
configuration permits capacity
expansion through the integration
of additional hot-swappable
UPS modules.
- PMC modules
PMC modules for the power
classes 10, 20, 30 and 40
kVA are prepared for 482.6
mm (19˝) installation in
TS 8 server racks.
- Maximum availability
The "n+1" system architecture
means that there are always
at least two modules able
to share the critical load.
If any module should fail,
the other modules automatically
take over the whole connected
load without interruption.

"n+1" System Architecture
Integration of up to 3 modules
in the IT rack or separate battery
enclosure
Modules can be retrofitted on
a hot-swapping basis, without
needing to switch the system
to a bypass. Stored energy times
can be tailored to the individual
application.DPA
The distributed parallel architecture
comprises integrated control
electronics for rectifier, booster,
inverter and static bypass.
The CPU, furthermore, possesses
parallel intelligence for enhanced
reliability.
