Conceptpower DPA 500 100 kW – 3 MW The modular UPS – now up to 3 MW


The UPS for those who need zero downtime

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 3 M W 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 3 MW 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.


Online Swap Modularity

Modules added to expand capacity are available right away – and existing modules remain online throughout the upgrade.

The lowest total cost of ownership

    The Conceptpower DPA 500 boasts the lowest cost of ownership of any UPS system by offering energy efficiency, scalability and ergonomic design to enable easy serviceability.

    It can be sized to align closely with prevailing IT requirements, but can be added to incrementally as IT needs grow. This means that you only power and cool what you need. The resulting savings in power usage over the service life of the UPS are substantial.

    Rack-mounted configurations can be right-sized by inserting or removing ‘online-swappable’ modules while the systems remain online, enabling power to be added as requirements grow without any footprint penalty. This makes servicing simple as modules can be replaced without powering down.

    Together with the excellent efficiency rating (up to 96 %) of the product, all these factors gives the Conceptpower DPA 500 the lowest total cost of ownership of any similar UPS system.


frames in parallel can be scaled to provide 3 MW of clean and reliable power.

Sized to fit your needs

Designers often over-specify UPS systems to take account of future demand growth. With the Conceptpower DPA 500, modules can simply be added in parallel to increase the system’s total capacity. The Conceptpower DPA delivers power protection from 100 to 500 kW (one to five modules) in a single cabinet. Cabinets can operate in a parallel configuration to build a system of up to 3 MW.

The Conceptpower DPA 500’s horizontal and vertical scalability allows:

–Flexible power upgrades and downgrades
– Easy maintenance
– Pay as you grow

Protecting power has never been easier

True, online-swap modularity enables the safe removal and / or insertion of Conceptpower DPA modules without risk to the critical load and without the need to power down or transfer to raw mains supply. This unique feature directly addresses today’s requirement for continuous uptime. The ability to online-swap modules in a Conceptpower DPA system significantly reduces its mean time to repair (MTTR) and simplifies system upgrades. The modular approach pays off too when it comes to serviceability and availability – online swapping of modules means you don’t have to switch off or switch to bypass during replacements, so there is no downtime.

Installation and service is easy too: The straightforward concept of the Conceptpower DPA simplifies every step of the deployment process, from planning, through installation and commissioning to full use. Flexible set-up and fast maintenance means lower operating and maintenance costs. The UPS is fully front serviceable.



Mean time between failures (MTBF) and mean time to repair (MTTR) are common parameters in the UPS industry and both impact system availability. Modular UPS designs minimizes the system‘s MTTR. ABB’s Decentralised Parallel Architecture allows the modules to work as one system but without interdependence. In the unlikely event that one UPS module were to fail, the overall system will continue to operate normally, but with one module fewer of capacity. The failed module is fully disconnected and cannot impact the operating modules. Quick and simple repair by swapping modules, which can be held as spares on-site or at a nearby service center, minimizes the system‘s MTTR.

This online-swap technology, along with significant reductions in repair time, can also achieve the so-called six nines availability (99.9999 percent) – highly desirable for data centers in pursuit of zero downtime.

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. Inventory levels of specialist spare parts are reduced.

up to 3MW

High efficiency

The scalability of the modular architecture can deliver major reductions in electricity consumption and CO2 emissions. Not only that, but a class-leading energy efficiency of up to 96 % significantly reduces system running costs and cooling costs. But, more importantly, the efficiency is optimized with a very flat efficiency curve that enables significant savings under every working condition.

Online-swappable modules

Every UPS module has a separate display. Additionally, a touchscreen display on the system level offers the opportunity of directly monitoring key functions. With both displays in place (module and system level), the UPS offers full user friendliness without making compromises on robustness.

Uninterrupted uptime for Tier IV Data Centers

Our modern society is now largely built on a foundation of data. Health authorities, banks, government departments, retail outlets and almost every other organization that touches our lives rely on the safe storage of enormous amounts of data. And safe data storage needs a rock-solid supply of power such as that shown in this reference example.

In a Tier 4 data center, it must be possible to undertake infrastructure work without disrupting the critical load. This requires simultaneously active distribution paths, typically in a system + system configuration. Electrically, this means two separate UPS systems in which each system has N + 1 redundancy. The sample reference scenario, 1200 kW Tier 4, illustrates one possible example of how the Conceptpower DPA 500 can be used to create a high-performance IT infrastructure.
Reference example of a data center application: The system flexibility allows upgrading or downgrading power capacity according to your needs.

Extra modules can be added while the system is powered up to make it up to 3 MW.
