Safe Swap Modules
28 March 2011 Conceptpower DPA 5
Safe-swap: hot insertion and removal of modules from ahost system without removing power.
In a redundant Power Protection SystemSafe-swap is achieved only if amodule may be added or replacedWithout interrupting the power to the Load and w/o having to transferthe load to the raw mains (by-pass).
High availability of power protection systems Safe scaling-up of system Easy fault recovery

Power Protection Parallel Architectures
Parallel System Architectures are designed to increase Power Protection Availability, which cannot be achieved by STANDALONE UPS’S.
These two architectures differ by the level of decentralization of their building blocks.
There are two basic Power Protection Parallel Architectures available today:
Parallel Architecture
• Central Parallel Architecture (CPA) and
• Decentralized Parallel Architecture
(DPA)TM

1. Optimize capital investment and available space Pay-as-you-grow solution lowers your capital costs and increases utilization rates, while
innovative rack-based technology frees up space previously needed for infrastructure support.2. Adapt to ever-changing power requirements
No need to abandon previous investment when power density needs increase or if physically moving your data centre. Adapt to changing wattage requirements in your racks with single- or multi- branch rack-mount power distribution units.3. Accelerate speed of deployment
Electrical and physical modularity allows for rapid installation with minimal engineering.4. Lower the cost of service contracts
Simplicity of system design and intelligent modular parts lessen the dependency on expensive service contracts.5. Increase availability
Specifically engineered to deliver higher availability through proactively designed, building block architecture and reduced MTTR

6. Decrease mean-time-to-recovery (MTTR) Compartmentalize potential failures with system components consisting of intelligent,
maintainable modules for quick fault recovery.7. Plan for a power density that is increasing and unpredictable
Eliminate hot spots in your data centre caused by higher power densities by targeting availability where you need it most.
8. Minimize points of failure between the UPS and the critical load Move redundancy closer to the load and prevent the majority of failures that cause critical load downtime.
9. Minimize human error Simplicity of design and intelligent modules increase system availability by mitigating human error: the number one cause of critical load downtime.
10. Decrease the operating costs With efficiency up to 96% (double conversion mode), the operating costs for a Conceptpower DPA modular UPS can be >40% less compared to those for a previous generation.
10 reasons for choosing a Newave modular UPS
Conclusion
28 March 2011 Conceptpower DPA 30
With the modular, safe swap UPS systems, you can build your own IT-Facility to meet simultaneously and most accurately:
1) Higher Availability
2) Unmatched flexibility to changes
3) Reduced footprint
4) Lowest TCO
5) Product standardization
AND ALL THIS AT BEST POSSIBLE COST
