The mission for increased availabilityAdvantages of the modular UPS concept

Add redundancyto the system

Ø Modular architecture introduces redundancy to the system automaticallyØ With decentralized paralleling architecture all modules are automatically redundant

with each otherà single points of failure in the UPS are eliminated

Minimize chancefor human error

Ø Simplicity of service + maintenance of ABB’s modular UPS mitigates human errorØ Modular architecture allows for implementation of simple and standardized power

protection and service concept across installations

Select high quality,reliable equipment

Ø Use reliable double conversion UPS technologyØ High “Swiss made” quality with 20 years experience on modular UPS

Minimize oreliminate need fordowntime

Ø UPS with modular architecture secures concurrent maintenanceØ With decentralized paralleling architecture all modules are capable to function

independentlyØ With on-line swappable modules, critical load does not need to be shut down or

transferred to raw mains during when UPS is being serviced

Secure simplicityand easiness ofservice

Ø Modular UPS allows also for simplifying and standardizing the complete serviceconcept across installation and sites!

Ø Same technology base and UPS concept can be used across load segments andapplications!

UPS service with online swappable modules:

§ Concurrent maintenence by swopping the modules

§ Concurrent repair by swopping the module

§ Limited spare parts inventory in quantities,

different articles and total value

§ Minimized human errors

§ Standardised service training

Operator training can be standardized and simplified since theUPS system is a standard solution.

Standardization benefitsOperation and maintenance

Conceptpower DPA 500Advantages of the modular UPS concept

Ø Combines the right-sizing approach with scalability,Ø Pay-as-you-grow solution lowers your capital costs and increases

utilization ratesØ Innovative technology allows for maximal power density that frees

space for other critical equipment.

Ø Electrical and physical modularity allows for rapid installation withminimal engineering.

Ø Same product and technology base can be selected to match theneeds of each data center and each load segment

Ø Modular architecture allows for implementation of simple andstandardized power protection and service concept acrossinstallations.

Ø On-line swappable modularity ensures need for scheduled andunscheduled downtime is minimized

Optimize and save on capitalinvestment

Accelerate speed ofdeployment

Decrease complexity andcosts of service andmaintenance

Decrease the operating costs

Ø With efficiency of 96% in double conversion and 99% in ECO mode,the operating costs can be >40% less compared to UPS of previousgeneration

Ø Increased availability and load uptime result in increased utilization

§ Frames can be connected in parallel to achieve 3 MW system total power.§ Multiple benefits follow from the advanced scalability:

§ Adding capacity to system is easy§ Adding redundancy to increase availability and reliability becomes easy§ Standardizing UPS system to serve load segments of different sizes is

reality

Benefits of standardizationSavings w/o surprises both when building and when operating a data center

Modular scalability enables the users with varioustypes and sizes of data centers to:Ø Optimize the solution according to the needs of

each data center or each load segmentØ Increase the system availability and gain

savings due to simple and standardized powerprotection concept

Ø and due to very efficient service conceptSmall or big

§ To maximize system efficiency the inverter chargersshut down after the bulk charge is complete. Thenthe low power float charger continues to charge thebatteries to 100% charge

§ The float charger cycles to maintain the float voltageon the batteries at 780VDC (adjustable to suitspecific battery chemistry)

§ If a float charger fails the inverter chargers willmaintain the battery charge. Normal inverterredundancy applies during charger function
