Conceptpower DPA 500 100 kW–3 MW

The modular UPS – now up to 3 MW

ABB’s Conceptpower DPA 500 is a high-power, modular and transformer-free UPS system for organizations who need zero downtime. The UPS is built using true online double conversion technology and provides low cost of ownership.

True modularity up to 3MW
Now you can have a UPS size to exactly fit your needs: The Conceptpower DPA 500 is the only modular UPS on the market that can easily be scaled up to provide 3MW of clean, reliable power. This scalability means that there is no need to over-specify the original configuration as power modules can simply be added, as needed, in the future.

True parallel architecture

Reliability and availability are ensured by the Conceptpower DPA 500’s proven Decentralised Parallel Architecture (DPATM). Each module contains all the hardware and software required for full system operation. They share no common components. Each UPS module has its own independent static bypass, rectifier, inverter, logic control, control panel, battery charger and batteries. With all the critical components duplicated and distributed between individual units, potential single points of failure are eliminated.

DPA 250 S4 (50 kW – 1,500 kW)

The most energy-lean UPS on the market

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 sets the standard for the next decade of UPS progress with advanced features such as its transformer-free IGBT converters that feature three-level topology with interleaving controls to enable market-leading efficiency of 97.6 percent for the UPS module. This high efficiency reduces operational costs and minimizes environmental impact.

This modular UPS is based on decentralized parallel architecture (DPA™), where every UPS module is practically its own UPS, having all the essential functional units needed for independent operation. DPA increases system reliability and availability compared to other modular UPS solutions in the market, as there is inherent redundancy between the UPS modules on all functional levels.

The DPA 250 S4 is specially designed for critical, high-density computing environments such as:

  • Small- to medium-sized data centers
  • Commercial buildings and general IT applications
  • Healthcare facilities
  • Railway signaling applications and airports

and medium power applications

All-in-one power protection solution

ABB’s DPA UPScale ST is available for high density applications requiring an all-in-one power protection solution that includes UPS modules, maintenance bypass, batteries, I/O terminals and communications. A single system delivers power protection from 10 kW to 200 kW in 10 kW or 20 kW modular steps. For a continuously growing midsized infrastructure, DPA UPScale ST can be paralleled horizontally to increase the capacity up to 400 kW. The ability to increment the power as the critical load grows optimizes the operating efficiency and reduce the initial cost for installations.

Product Features

  • Online double conversion UPS
  • Power range from 10 kW to 200 kW in a single frame
  • Redundant capacity (N+1) per frame
  • Up to four frames in parallel
  • Online swap modularity (OSM)
  • Up to 96% online efficiency
  • Eco-mode efficiency ≥ 98%
  • Low input harmonic distortion (THDi < 3%)
  • High power density (472 kW/m²)
  • Flexible battery configuration
  • Remote control and monitoring options

Megaflex DPA UPS

Meet the best and most reliable UPS on the market

The on-line double conversion MegaFlex DPA UPS provides the best power protection for your critical infrastructure from 250 kW to 1,500 kW.

This modular UPS is specifically designed for critical high-density computing environments across private and public enterprise, as well as data centers for colocation, hosting cloud and telecommunications.

The modular UPS is based on ABB’s decentralized parallel architecture (DPA™). This innovative system means every UPS module is practically its own UPS with all the essential functional units needed for independent operation. DPA provides full redundancy and fault tolerance in a way that is unique amongst UPS vendors. This results in increased system reliability and availability that outperforms every other modular UPS solution on the market.

PowerLine DPA 20–120 kVA

Full power for industrial applications

For many industries, the consequences of electrical power loss can be disastrous: Production lines may have to go through a complex and costly restart; expensive product may be ruined; valuable production time can be lost; process equipment can be damaged; and safety issues may arise. Because a reliable supply of clean power usually cannot be guaranteed by the grid, ABB’s PowerLine DPA UPS (uninterruptible power supplies) makes sure that the operation of industrial applications keeps running continuously as it should.

PowerLine DPA is an online double conversion UPS and makes the advantages of ABB’s unique modular UPS architecture available for locations that are usually rough on electronic equipment. PowerLine DPA is based on ABB’s Decentralized Parallel Architecture (DPA) that ensures the very best UPS design in terms of availability, flexibility, cost and ease of use.

Its robust design is suitable for industrial plant environments that have a variety of temperatures, dust, moisture and corrosive contaminants. The PowerLine DPA is designed to have a design life of 15 years.

DPA – the very best UPS design
With DPA, the UPS is modularized and each module has all the hardware and software needed for autonomous operation: rectifier, inverter, battery converter, static bypass switch, backfeed protection, control logic, display, and mimic diagram for monitoring and control. A module’s output is not affected by failures elsewhere in the UPS. If one module is lost, the others take up its load. In other words, a multimodule system is fault tolerant and there are no single points of failure.
