How to minimize Total Cost of Ownership (TCO)

Save valuable floor space

Modularity lends itself well to keeping UPS footprint small, too – ideal where real estate is limited and expensive.

A modular UPS rack has a small footprint and when extra modules are added, no extra floor space is taken up.

Optimize your battery capacity

Run-time and battery sizing can be exactly fitted to what is required. A separate battery allows the system to be upgraded and autonomy preserved, while not compromising availability.
Full redundancy is only achieved with a redundant battery. If a common battery may be required, ABB’s modular UPS allow flexible blocks per string.

Reduce installation and maintenance costs

The modular approach makes installation and commissioning easy. Standardized modules reduce inventory levels of specialist spare parts and simplify system upgrades. This approach pays off too when it comes to serviceability and availability as service personnel do not need special skills and human error is reduced. Spares can be held on-site or at a nearby service center. Not only does this improve availability but it also reduces cost as service engineers spend less time on-site, and any risks of data or production loss are minimized. The only UPS elements common to all modules are contained in the mechanical frame that accommodates the UPS modules – I/O connection, customer interface signaling, maintenance bypass and, in some models, a system display. These elements are standardized in order to minimize maintenance costs.

Optimize your investments

As UPS power requirements change – if a data center is expanded, say – modularity makes it really easy to add modules and increase the power capabilities. You don’t have to overspecify the initial configuration to cater for future expansion, you just add modules when needed.
This means that you only cable, power and cool what you need. Power consumption is a topic of great concern for most operators and the energy savings made by the modular approach over the service life of the UPS are substantial.

Save energy costs

The modularity and scalability described have a major positive impact on achieving a low cost of ownership, but costs are held down too by designs that have best-in-class energy efficiency. ABB’s Conceptpower DPA 500, for example, operates with an efficiency of up to 96 percent. Its efficiency curve is very flat so there are significant savings in every working regime. Further, cooling costs can be substantial and, because less power is consumed, high-efficiency modular UPSs require less cooling effort, creating further savings.
