The DPA 250 S4 has a high-efficiency, modular architecture that offers best reliability for environmentally conscious organizations that also need zero downtime and low cost of ownership. The DPA 250 S4 is specially designed for critical, high-density computing environments such as small- to medium-sized data centers.
High efficiency reduces total cost of ownership (TCO)
Selecting a UPS with high efficiency saves operational expenditures over the service lifetime and minimizes the impact it has on the environment.
Featuring superior 97.6 percent UPS module efficiency and 97.4 percent system efficiency, the DPA 250 S4 reduces energy losses that create pure costs as direct electricity spend and costs for cooling. Thanks to three-level interleaved technology, the DPA 250 S4 achieves an efficiency of over 97 percent in a wide operating range.
Under operating conditions where the load is low compared to UPS total capacity, efficiency typically suffers and relative power losses are increased. Under these conditions, by using ABB’s intelligent Xtra VFI – double conversion mode, the DPA 250 S4 can step up the system efficiency by optimizing the number of modules used in double conversion mode to feed the load. In case of a load step, more modules are switched automatically in milliseconds to online mode to secure the critical load.
Uninterruptable power – scalable from 50 kW up to 1.5 MW
Featuring the most reliable DPA architecture, each module is capable of working independently. Modules include all necessary functional parts, such as rectifier, inverter, battery converter, static bypass and back-feed protection. This allows the modules to be fully redundant with each other for maximal reliability. The DPA 250 S4 300 kW cabinet can host up to six 50 kW modules for 300 or 250 kW N+1 redundant power. Up to five 300 kW frames and up to 30 modules can be paralleled for an amazing 1,500 kW of uninterrupted power.Up to six 250 kW frames and up to 30 modules can be paralleled for an amazing 1,500 kW of uninterrupted power. Secure ring communication ensures there is no single point of failure in the system.
Online swappable module for continuous uptime
DPA architecture enables UPS modules to operate completely independently of each other. This means that in case one UPS module needs to be removed or added to the system, this can be managed fast and seamlessly.
Short service time
The UPS modules have virtually no wiring. The circuit boards and other internal components have been positioned in such way that consumable parts that may require replacement during service life are easily extractable – making servicing safer and faster. It takes only a few minutes to extract a module, replace consumable parts, insert it back to the system and turn it back online.
