Three-phase UPS systems scale up to 100kW

The PowerWave9000DPA represents another important advance in UPS technology, with significant enhancements to the decentralised parallel architecture.

Uninterruptible Power Supplies is releasing the PowerWave9000DPA - the next generation of the company's highly acclaimed three-phase rack-format modular UPS products.

The PowerWave9000DPA represents another important advance in UPS technology, with significant enhancements to the company's renowned state-of-the-art decentralised parallel architecture (DPA).

Decentralised parallel architecture (DPA) embraces the concept of removing single points of failure by connecting in parallel, independent, self-reliant, three-phase UPS modules.

The UPS modules are housed, and are automatically connected in parallel, within an attractive 19in rack format cabinet complete with independent internal (or external) battery set(s) per module and an integrated input/output distribution section.

The PowerWave9000DPA UPS system delivers a scalable solution with hot-swap modules of 8, 12, 16 and 20kW permitting selectable load power capacity from 8 to 100kW (5 x 20kW), all in one 19in rack format cabinet, enabling an unprecedented power density of 170kW/m2.

Scalability can be further enhanced by connecting cabinets in parallel to match load requirements up to several hundred kilowatts.

Battery standby is also scalable, with autonomy times from five minutes to several hours available.

The modular and scalable design of the PW9000DPA permits the user to easily increase the UPS capacity in cost-effective incremental steps to match the needs of the critical load.

Significant improvements to the reliability of UPS power support can be gained by operating the PowerWave9000DPA in a parallel-redundant (N+n) mode.

In the unlikely event of a UPS module failing, it automatically isolates itself from the supply and the remaining healthy paralleled modules continue supporting the critical load up to their collective capacity.

The true UPS module and battery hot-swap capability of the DPA architecture facilitates extremely low mean time to repair (MTTR) which, in turn, allows "best in class" power availability of "six nines" (99.9999%).

In summary the PowerWave9000DPA is the most advanced UPS solution available for business critical applications offering reduced single points of failure, class leading availability, the smallest footprint in its class, high efficiency (95 to 96% efficiency between 30 and 100% full load rating), low whole-life costs and very low input current harmonic distortion (2 to 3% THDi between 30 and 100% full load rating).

The PowerWave9000DPA is also blade server friendly - capable of supplying loads with a power factor up to 0.9 leading without the need for UPS derating.
