The portfolio supports 800 VDC distribution, power protection, cooling optimization and hybrid AC/DC facility designs.
ABB has announced Infinitus, a portfolio of direct current (DC) power solutions for data centers with increasing electricity and power-density requirements. The portfolio supports DC and hybrid AC/DC architectures intended to improve energy efficiency, reduce power infrastructure requirements and increase the power available for computing equipment.
The International Energy Agency (IEA) expects global data center electricity demand to more than double by 2030. ABB estimates that DC distribution could be used in approximately 25% to 40% of new data center capacity installed in 2030.
Next-generation AI chips are expected to require 1 MW or more per rack compared with nearly 200 kW today. This increase is driving interest in DC architectures that can support higher power levels while reducing conversion steps and associated losses.
An 800 VDC distribution system can reduce infrastructure requirements by eliminating some conversion stages used in conventional alternating current (AC) systems. A report from BCG and ABB found that DC distribution can improve energy efficiency by more than 5% and increase the space available for computing racks.
For a 500 MW data center, a 5% efficiency improvement would make 25 MW more available for IT loads. ABB estimates that this could represent more than $300 million in potential additional annual revenue. Over one year, the energy saved by a 5% efficiency improvement at a 500 MW data center campus would be equivalent to the electricity used to power Washington, D.C. for nearly one week.
ABB said its work on Infinitus includes collaboration with chipmakers, hyperscale customers, supply partners and industry organizations to support the development of DC architectures. The portfolio is designed for DC-native and hybrid AC/DC data center configurations and is also intended for other energy-intensive applications such as large-scale manufacturing, renewable energy and marine operations.
Infinitus is an integrated DC portfolio that covers power delivery from the electrical source to the rack. It includes ABB solid-state transformer technology along with solid-state circuit breaker and static medium-voltage UPS technologies.
The Infinitus DC portfolio includes five main areas:
- Medium-voltage powertrains — Deliver power from the grid or on-site generation to the facility.
- DC sources and power quality — Convert AC power to DC and move conversion equipment outside the data hall.
- DC power distribution — Distribute power to support higher power density within the available facility space.
- DC power protection — Protect operators, AI servers and other equipment from DC overcurrent conditions.
- Cooling optimization — Use DC-connected variable-speed drives and motors to manage energy use in facility and IT equipment cooling systems.
ABB works with customers to develop solutions based on their power requirements, facility layouts and energy sources. The portfolio can complement AC systems and support different combinations of AC and DC infrastructure.
The architecture is intended to support the power requirements of high-density AI data centers. ABB expects the first DC-native facilities using the complete Infinitus portfolio to be installed and operational within two to three years, with several main components scheduled for production during the next 12 months.
The launch continues ABB’s collaboration with NVIDIA, announced in October 2025, on 800 VDC power architectures for gigawatt-scale AI facilities. ABB said it has more than 25 years of experience with DC systems and more than 700 patents covering areas such as renewable energy, power generation, energy storage, motors and drives.
